Cinematic legend and Sam Raimi regular Bruce Campbell plays Darkman in the final shot.

Director John Landis and actress Jenny Agutter both have cameos in this movie as doctors. And let us not forget that John Landis directed An American Werewolf in London and Jenny Agutter starred in it. Jenny Agutter is not credited at the end of Darkman, only John Landis is.

Sam Raimi wanted Bruce Campbell to star, but was overruled. There are clear similarities between Liam Neeson's performance and Bruce Campbell's decomposed alter-ego in Army of Darkness (and as anyone with a brain knows NOW, Bruce Campbell is a genius who could have played the role perfectly).

During a scene in the movie, Darkman cries out "JULIE.". The voice of Darkman for this scene was not done by Liam Neeson, but was in fact done by Bruce Campbell. http://en.wikipedia.org/wiki/Darkman#Darkman_Trivia
