Early Childhood and Family Background
John Glover was born in Kingston, New York, but spent much of his childhood in Salisbury, Maryland, on the state’s Eastern Shore.2
He was the son of John Soursby Glover Sr. and Cade Glover. His father worked as a television salesman. Glover grew up as an only child and developed an early fascination with entertainment.
In an interview with Playbill, he recalled being interested in movies and particularly enjoying stories about what happened behind the scenes. He was curious about how films were made and how performers brought characters to life.
One early experience that stayed with him was seeing the touring production of Oklahoma! when he was in third grade. However, that experience did not immediately convince him to become an actor.
For much of his youth, acting remained an interest rather than a clear career plan.
Glover attended Wicomico High School in Maryland. Like many young people, he had to decide what he wanted to do with his life after finishing school.
His eventual path into professional acting was not the result of growing up in a famous Hollywood family. Instead, it developed through education, theatre experience and the opportunities he encountered while studying.
These early experiences helped him discover that acting could be more than a personal interest. It could become a profession.
Education and the Decision to Become an Actor
Glover attended Towson State Teachers College, now known as Towson University. He initially planned to become a teacher rather than pursue a career in entertainment.
However, his time at college introduced him to theatre in a more serious way.
After his first year, Glover participated in summer stock theatre at the Barter Theatre in Abingdon, Virginia. Summer stock productions provide actors with opportunities to perform in plays over a relatively short period, often working on several productions during a season.
One of his early stage experiences involved playing the lead role in Look Homeward, Angel. The production included actor Ned Beatty, who played his father.
Glover later recalled that working with experienced performers helped him realise that acting might be a realistic career.
That experience changed his direction.
He completed his education and moved to New York City to pursue professional opportunities. Like many actors starting out in the theatre world, he had to develop his skills and establish himself in a competitive industry.
He also studied at the Beverly Hills Playhouse under acting teacher Milton Katselas.
His formal training and stage experience became important foundations for a career that would eventually span theatre, film, television and animation.
Building a Career in Theatre
Theatre remained an important part of Glover’s professional life even after he became familiar to television audiences.3
Stage acting requires performers to sustain a character throughout a live performance. Unlike film and television, where scenes can be filmed repeatedly and edited later, theatre actors must respond to the other performers and audience in real time.
Glover developed a reputation for taking on challenging characters and bringing a distinctive personality to his performances.
One of the most significant productions of his career was Love! Valour! Compassion!, the play written by Terrence McNally.
The production earned considerable recognition, and Glover won the 1995 Tony Award for Best Featured Actor in a Play. He played the dual roles of John Jeckyll and James Jeckyll.
He later reprised the roles in the film adaptation released in 1997.
The award marked a major achievement in his career and demonstrated that his reputation extended well beyond television villains.
Glover’s success on Broadway also reflects his ability to move between different kinds of storytelling. While some audiences know him primarily for sinister characters, his stage career includes work that explores humour, relationships and complex human emotions.
John Glover’s Film Career
Glover’s filmography includes several productions that have become familiar to audiences over the years.
One of his best-known film roles came in Gremlins 2: The New Batch, released in 1990.
He played Daniel Clamp, a wealthy businessman whose high-rise building becomes the setting for the film’s chaotic events. Clamp is an eccentric character who owns a large media and business empire.
The role allowed Glover to demonstrate his comic abilities.
Interestingly, he reportedly chose to play Clamp as an eccentric but generally likable figure rather than simply portraying him as a deeply unpleasant businessman. The decision helped give the character a distinctive personality.
He also appeared in Scrooged in 1988, playing Brice Cummings. The film starred Bill Murray and became a popular modern adaptation of Charles Dickens’ A Christmas Carol.
Other film credits include In the Mouth of Madness, Payback, Batman & Robin and Love! Valour! Compassion!
In Batman & Robin, released in 1997, Glover played Dr. Jason Woodrue, a scientist associated with the creation of Poison Ivy.
These roles show how often Glover has worked within stories featuring unusual characters, larger-than-life personalities and moral ambiguity.
His ability to combine humour with an unsettling edge made him a natural fit for many of these productions.

Smallville: The Role That Made Him a Television Favourite
For many viewers, John Glover will always be Lionel Luthor.
Smallville premiered in 2001 and explored the early life of Clark Kent before he became Superman. The series followed Clark’s experiences in the fictional town of Smallville as he discovered his abilities and developed relationships that would shape his future.
The show also explored the rise of Lex Luthor, who would eventually become one of Superman’s most famous enemies.
Glover played Lionel Luthor, Lex’s wealthy and powerful father.
Lionel was a businessman whose ambition and desire for control affected almost everyone around him. He could be manipulative and ruthless, but his relationship with Lex was also complicated by family expectations and personal conflicts.
The character was central to many of the show’s most important storylines.
Glover’s performance was particularly effective because he did not play Lionel as a simple villain. He gave the character an imposing presence while allowing moments of vulnerability and uncertainty to emerge.
At times, Lionel appeared to be an obstacle for Clark Kent. At other moments, his actions suggested that he understood more about Clark’s abilities and potential than he was willing to admit.
His relationship with Lex was equally complex.
Lionel wanted his son to become powerful and successful, but his controlling behaviour often damaged their relationship. Their conflicts helped explain some of the bitterness that eventually shaped Lex’s character.
Glover’s performance brought a sense of unpredictability to the series. Viewers could never be entirely certain whether Lionel was trying to help someone, manipulate them or protect his own interests.
That uncertainty helped make him one of the show’s most compelling characters.
Glover appeared in the series across multiple seasons and returned for its later storylines. Lionel’s death in the seventh season became a major turning point, although Glover later appeared again through the show’s alternate realities and subsequent developments.
His work on Smallville remains one of the most memorable portrayals of Lex Luthor’s father in live-action television.
John Glover as the Riddler
Glover’s connection to the DC universe extends beyond Smallville.
He voiced the Riddler in several animated productions, including Batman: The Animated Series, Superman: The Animated Series and The New Batman Adventures.
The Riddler is one of Batman’s most recognisable enemies. The character is known for using puzzles, riddles and elaborate schemes to challenge the Dark Knight.
Voice acting requires a different set of skills from live-action performance. Actors must convey personality and emotion through vocal delivery alone, without relying on facial expressions or physical movement that an audience can see.
Glover’s distinctive voice and ability to suggest intelligence and menace made him well suited to the role.
His work as the Riddler also demonstrates the breadth of his connection to superhero storytelling.
Between Lionel Luthor in Smallville, Dr. Jason Woodrue in Batman & Robin and the Riddler in animation, Glover has portrayed several notable characters connected to the worlds of Superman and Batman.
For fans of DC adaptations, his career is an interesting example of an actor appearing in different versions of the same fictional universe.
Other Television Roles Beyond Smallville
Although Smallville remains one of his best-known television projects, Glover has appeared in numerous other series.
His television credits include L.A. Law, Frasier, The Good Wife, The Good Fight, Evil, Lucifer, Heroes and Fear the Walking Dead: Dead in the Water.
He received five Primetime Emmy nominations for his performances in television productions.
These nominations included work in An Early Frost, Nutcracker: Money, Madness & Murder, L.A. Law, Crime & Punishment and Frasier.
The range of projects is notable because Glover has worked across different genres. His roles have included dramatic characters, eccentric personalities and figures whose intentions are difficult to understand.
In Heroes, for example, he appeared as Samson Gray. His later television work has included guest appearances in established series and projects with darker themes.
He also appeared in And Just Like That…, the continuation of the Sex and the City television franchise.
These projects demonstrate that his career did not end when Smallville finished in 2011.
Where Is John Glover Now?
John Glover has continued to work in entertainment beyond his most famous television role.
His more recent credits include appearances in And Just Like That… and the 2025 horror film The Home. These projects show that he has remained involved in screen acting long after the conclusion of Smallville.
Glover has also spoken about his desire to continue acting as he grows older.
In a 2023 appearance on Michael Rosenbaum’s Inside of You podcast, he discussed ageing in the entertainment industry, his experiences on Smallville and his wish to remain professionally active.
The conversation offered a glimpse into how he views acting as a lifelong pursuit rather than a career that must end at a particular age.
His work has also maintained a connection with theatre. He has returned to Towson University to work with drama students, helping younger performers learn about the profession and the importance of enjoying the craft.
For fans asking where he is now, the clearest answer is that Glover has continued to pursue acting and maintain his connection with theatre. He is not defined solely by his work on Smallville.
However, it is important to distinguish between confirmed professional credits and speculation about his current schedule. Not every appearance or reported project means that an actor has a new series or film in development.
His career remains notable for its longevity and variety.
John Glover’s Personal Life
Glover has generally kept much of his private life away from the centre of his public career.
He married sculptor Adam Kurtzman in 2016 after a long-term relationship. The couple’s relationship has occasionally been mentioned in biographical profiles, but Glover’s professional work remains the main focus of his public identity.
He has also been involved with Alzheimer’s-related advocacy.
His interest in the cause is connected to his father’s experience with Alzheimer’s disease. Personal experiences with a family member’s illness can lead people to support organisations that raise awareness and help affected families.
Glover’s involvement demonstrates that his public life extends beyond entertainment.
He has also maintained a relationship with Towson University, where he has returned to work with students. This connection reflects the importance of his early education and the theatrical experiences that helped him become an actor.
His career offers a reminder that professional success can include more than awards and well-known screen roles. Supporting younger performers and contributing to causes that matter personally can also become meaningful parts of a public figure’s life.
What Makes John Glover Such a Memorable Actor?
One of Glover’s greatest strengths is his ability to portray characters with multiple layers.
His villains are rarely presented as entirely one-dimensional figures. Even when a character is manipulative or threatening, Glover can suggest the motivations and insecurities that influence their behaviour.
Lionel Luthor is an especially clear example.
His desire for power often made him dangerous, but his relationship with Lex added emotional complexity. The audience could recognise his ambition while also seeing how his choices affected his family.
Glover also has a distinctive screen presence. His delivery can be controlled and measured, which often makes his characters more intimidating than someone who constantly raises their voice.
His experience in theatre contributes to this quality. Stage work requires actors to understand a character’s motivations and sustain a performance over time.
His comic roles demonstrate a different side of his talent. Daniel Clamp in Gremlins 2: The New Batch was eccentric and entertaining rather than simply sinister.
The ability to move between these different styles is one reason Glover has maintained a long career.
