Sometimes funny, sometimes just sort of dumb Steve Martin-written and acted comedy about an nth -rate director making a film starring Eddie Murphy (sometimes great!) as Kurt Ramsey, a psycho action star. He doesn’t know he’s in the film. The really funny stuff involves “Mind Head” (Scientology) a bogus cult that dominates LA. That stuff is really funny as is Murphy’s psycho stuff and his work as his dumb, look-alike brother.
