Sunset Boulevard

Self-referential

This movie is about making a movie, portraying a former silent film star, Norma Desmond, who believes she can make a comeback, and has written her own script for a film in which she would portray Salome. When her script doctor, Joe Gillis, tells her she’ll never make a comeback, she shoots him in the back as though she thinks it’s only a stage gun. Her greatest role is playing herself pretending to be impersonating someone else.

Delusional

Norma thinks that Cecil B. DeMille at Paramount wants her to star in her movie about Salome, when DeMille only wants to rent her car.

Film noir

John F. Seitz could have filmed in color but a dark comedy film noir is more interesting in black, white, and shades of gray.
