Timecop was originally published as a three-part story, Time Cop: "A Man Out of Time", in the anthology comic Dark Horse Comics #1-3 (August-October 1992) and later a two issue comic book adaptation of the eponymous film published along with the film's release in September 1994. The film and its sequel were both written by Mike Richardson, the founder and publisher of Dark Horse Comics. His company published the adaptations which were themselves written by Mark Verheiden and drawn by Ron Randall. The film also spawned a video game in 1995 and a Timecop TV series in 1997.
