Credit you give yourself is not worth having. Thalberg would not allow his name on his pictures; the one exception being The Good Earth (1937), posthumously.
[Screenwriter Charles MacArthur, who was a close friend, commenting on
why Thalberg never took a producer's credit on his films]
Entertainment is Thalberg's god. He's content to serve him without
billing.
A story never looks as good as when the other fellow buys it.
If they don't want to come to the picture...you can't stop them.
[Instruction to the writers of the updated 'Camille', 1936]
The problem of a girl's past ruining her marriage doesn't exist anymore. Whores can make good wives. That has been proven.
Hit a fellow in old clothes with a snowball and it won't mean a thing. But dress a man up in tails and a silk hat and then knock his hat off, and you'll get a laugh.
