The Beat Generation is a 1959 American crime film noir from Metro-Goldwyn-Mayer starring Steve Cochran and Mamie Van Doren, with Ray Danton, Fay Spain, Maggie Hayes, Jackie Coogan, Louis Armstrong, James Mitchum, Vampira, and Ray Anthony.
[2] It is a sensationalistic interpretation of the beatnik counterculture of the "Beat Generation" (and is sometimes considered one of the last films noir to be produced.)
In the opening scene, a "beatnik" named Stan Hess (Ray Danton) sits at a table in a coffee house with a woman who begs him for his affection.
He scorns her, then encounters his father at another table, who announces his engagement to a younger woman who had also pursued Stan.
The rapist calls himself Arthur Garret, and as the two talk, he learns that Culloran is married, and sees his address on an envelope on the car seat.
They have a suspect, a beatnik called Art Jester (James Mitchum) who fits a description of 'The Aspirin Kid' but his alibi checks out.
Instead of coming to the club, though, he goes to Culloran's home and attacks his wife, Francee (Fay Spain), also telling her his name is Arthur Garret.
After an elaborate scuba-diving chase sequences, Culloran captures and beats up Garrett coming close to killing him before Baron intervenes.
I remember a copy of the script, many drafts in, where Zugsmith had meticulously crossed off police everywhere and had written in fuzz.
