1980 The Stunt Man

"While on the run from the police, Steve Railsback hides in a group of moviemakers where he pretends to be a stunt man. Both aided and endangered by the director (Peter O'Toole) he avoids both the police and sudden death as a stuntman. The mixture of real danger and fantasy of the movie is an interesting twist for the viewer as the two blend in individual scenes"iMDB
 
This hard to find Peter O'Toole film is the rarer Guild Home Video release. It is in very good condition.
