Gene Hackman playing two roles in Superman IV marks one of the most bewildering creative choices in cinematic superhero history. When
“Superman IV: The Quest for Peace”
premiered, Hackman not only reprised his famous Lex Luthor but, due to a last-minute production decision, unexpectedly provided the voice for Nuclear Man, adding an odd twist to an already troubled film.
Hackman’s Return and the State of the Superman Franchise
Gene Hackman had originally taken on the role of Lex Luthor in Richard Donner’s “Superman: The Movie,” admittedly more attracted by Warner Bros’ substantial offer than by passion for the source material. As he adjusted to the comic book tone during filming, Hackman found enjoyment and continued his involvement as Luthor in later sequels. Nonetheless, by the time he returned for “Superman IV” in 1987, the franchise was struggling. The previous installment, “Superman III,” delivered lackluster critical responses despite financial gains, and the “Supergirl” spinoff failed both commercially and with fans, suggesting that the series might be at its end.
In a bid to keep the saga alive, Warner Bros pressed forward with a fourth film. They managed to convince Christopher Reeve to return by promising him creative input, particularly on the script, which tackled nuclear disarmament—a theme reflecting the era’s anxieties. Hackman, who had skipped “Superman III,” agreed to reprise his villainous role. To his surprise, the production would soon ask more of him than he’d bargained for.

The Bizarre Birth of Nuclear Man and Hackman’s Second Role
“Superman IV” is remembered less for its box office performance and more for introducing Nuclear Man—a character that left many cinemagoers perplexed. The film’s plot involved Superman hurling a nuclear missile, rigged with Superman’s DNA thanks to a scheme by Luthor, into the sun, which led to the bizarre creation of this new foe. When Nuclear Man first appeared, audiences quickly noticed something odd about his voice: it sounded suspiciously like a distorted version of Hackman’s own.
Originally, English bodybuilder Mark Pillow was cast to portray Nuclear Man, bringing the menacing physicality but little acting experience. However, unexpected production changes in the late stages meant Pillow would have to lip-sync to dialogue pre-recorded by Hackman. Neither Pillow nor Hackman anticipated this direction, which was set in motion after filming had already begun.
“That was an odd, late choice,”

“Gene didn’t expect that, and neither did I. It led to a very wooden performance, which made it a challenge. All I was doing was following Gene’s voice, which gave me very little scope to do anything. To this day, I’m not completely sure why they made that decision.”
—Mark Pillow, actor
Confused Vision and Troubled Production
The inexplicable decision to have Gene Hackman playing two roles in Superman IV serves as a striking example of the film’s broader production issues. Even before settling on Hackman voicing Nuclear Man, director Sidney J. Furie shot numerous scenes with an earlier iteration of the villain, played by Clive Mantle, who more closely resembled the mutated comic book antagonist Bizarro. All scenes featuring Mantle were ultimately scrapped, and Mark Pillow took over as a new version of Nuclear Man, yet the director and producers seemed uncertain about how to shape the character.
The production’s lack of clear direction left Pillow in the awkward position of miming to Hackman’s lines, producing a performance that seemed wooden and detached. This confusion extended even to casting: after discarding the first Nuclear Man, the filmmakers selected a newcomer with no acting credits, only to later decide he should not deliver his own lines.
Legacy of a Puzzling Choice
Although the dual role of Gene Hackman in “Superman IV” is only one of the film’s criticized elements, it perfectly encapsulates the story behind its troubled creation. Attaching Hackman’s voice to a genetically engineered villain born from Superman’s DNA may have been meant as clever, but instead highlighted the film’s many missteps. Fans and critics alike have reflected on whether Christopher Reeve, having played Superman and provided the DNA that sparked Nuclear Man’s existence, might have been a more logical choice to voice the villain—although, as history has shown, logic was not always at play in the making of “Superman IV.”
Decades after its release, the strange decision remains a talking point for fans and an emblematic misstep for the franchise, underscoring how even blockbuster productions can unravel when creative vision is lacking. While the film ended the original “Superman” series, the curious case of Gene Hackman playing two roles in Superman IV continues to intrigue moviegoers and students of cinematic history alike.
