Fade to Black (1980)

 

A shy, lonely film buff embarks on a killing spree against those who browbeat and betray him, all the while stalking his idol, a Marilyn Monroe lookalike.

From memory: An usual thriller with an interesting premise is at times creepy, suspenseful and disturbing; meant as a homage it includes many cinematic references.

Halliwell (no star): "Violent, off-beat thriller that makes black jokes at the expense of movies."

Maltin*1/2: "Interesting idea ruined by excessive violence, poor performance by Christopher. Marilyn Monroe lookalike Kerridge...is like a rose in a cesspool."
