For most people, Gene Simmons will always be remembered as "The Demon," the fire-breathing, blood-spitting co-founder of legendary rock band KISS. With his towering stage boots, trademark tongue, and comic-book persona, Simmons became one of rock's most recognizable figures.
But while music made him famous, Simmons spent decades trying to carve out a second career in Hollywood, appearing in everything from cult action movies and thrillers to television dramas and family films.
Unlike many rock stars who made brief cameos as themselves, Simmons pursued acting with genuine enthusiasm, becoming a familiar face in 1980s and 1990s genre cinema.
His breakthrough came in 1984 with Runaway, directed by acclaimed filmmaker Michael Crichton. Starring opposite Tom Selleck, Simmons shocked audiences by playing the villainous Dr. Charles Luther, a ruthless high-tech criminal.
The role was a natural fit. Simmons possessed an imposing screen presence, and his larger-than-life personality translated surprisingly well to the role of a cold, calculating antagonist. While the film received mixed reviews, many critics singled out Simmons as one of its most memorable elements.
Following Runaway, Hollywood quickly realised that Simmons excelled at playing villains.
In 1987 he appeared in Wanted: Dead or Alive alongside Rutger Hauer. Simmons played terrorist Malak Al Rahim, delivering a performance that was both theatrical and menacing. The film has since developed a cult following, with Simmons' over-the-top villain becoming one of its standout attractions.
Throughout the late 1980s and early 1990s, Simmons became a regular fixture in action and thriller productions. He appeared in films such as Red Surf and Never Too Young to Die, the latter becoming infamous among cult movie fans for its bizarre tone and eccentric performances.
What made Simmons an unusual actor was that he rarely tried to escape his rock-star image. Instead, filmmakers often leaned into it. His deep voice, imposing stature, and naturally intimidating presence made him ideal casting for villains, gang leaders, and eccentric authority figures.
Television also became an important part of his acting career. Simmons appeared in shows including Miami Vice, Third Watch, and numerous guest appearances where his celebrity status added an extra layer of intrigue to his characters.
As the years progressed, Simmons increasingly embraced self-aware roles. Rather than fighting against public perceptions, he often played exaggerated versions of himself or characters that borrowed heavily from his public persona. This approach helped him remain visible even as his acting ambitions shifted toward reality television and business ventures.
The arrival of Gene Simmons Family Jewels introduced a new side of Simmons to audiences. While not an acting role in the traditional sense, the series transformed him into a television personality and brought his off-stage life into millions of homes. For many younger viewers, the reality show became their first exposure to Simmons, rather than KISS itself.
Looking back, Simmons never achieved the kind of Hollywood success enjoyed by musicians-turned-actors such as Cher or Will Smith. Yet his acting career remains remarkably varied and surprisingly influential within cult cinema circles.
Today, many of the films he appeared in are celebrated by fans of 1980s genre filmmaking. His performances in Runaway and Wanted: Dead or Alive continue to be rediscovered by audiences who appreciate charismatic screen villains, while his broader filmography offers a fascinating glimpse into a period when rock stars routinely crossed over into Hollywood.
For Gene Simmons, acting was never about abandoning the Demon. It was about finding new stages on which to perform. Whether playing a cybercriminal, a terrorist, a television personality, or simply a heightened version of himself, he brought the same larger-than-life energy that made him one of rock's most enduring icons.
