Prince of Darkness
John Carpenter directed and produced this horror movie giving Alice and Kane a cameo appearance. The story is taken in an old church which these scientist are trying to figure out this cylinder object in the basement that is filled with green goo. Supposedly it's an evil presence that is taken over animals and people. Alice and Kane play street people who are under it's spell. They seem to act as zombies so no dialoged but Alice uses his stage theatric of the slaying the cameraman from his Nightmare Return Tour. Only in this picture Alice takes the front end frame of a bicycle and jams it through one of the scientist.
Little trivia: the scientist was that geeky character who use to be on the 80's series "RipTide".
