"The Loved One"
The in-twist is that many of the actors are/were gay (and it's 1965 - I'd placed it in late '50s). But any movie with Rod Steiger as Mr. Joyboy, Gielgud, Coburn, Robert Morley [!!] Well..
One of novelist Evelyn Waugh's most vicious satires, set among the last resting places for people and animals in Hollywood. Morse comes to Hollywood to visit his uncle (Gielgud), a movie art director who hangs himself when he loses his job. Morse is then in the hands of Morley and twin funeral directors (one for humans, one for animals), both played by the sur-really funny Winters. A wickedly wry look at death and Hollywood. Script by Southern and Isherwood.
Dana Andrews, Milton Berle, James Coburn, Sir John Gielgud, Robert Morley, Rod Steiger, Paul Williams
Director: Tony Richardson
A precious treatment of the Murican Way of Death and attitudes toward capitalism, sex, religion, Hollywood, and other sacred cows...
