"Dirty Harry" Callahan first appeared in a video game in 1990 on the NES. Developed by Grey Matter Inc and published by Mindscape the game titled “Dirty Harry” was a simple side scroller, featuring arbitrary platforms, shooting and fist fight mechanics. Apart from its basic vigilante cop narrative and some digitised soundbites from the films, there was very little to link it to the source material. Overall this was hardly a fitting debut for the character that has defined Clint Eastwood’s career and spawned five motion pictures. Beyond a brief appearance on a themed pin ball machine in 1995, Harry Callahan has remained conspicuously absent from the video games genre.
