—Stop blaming Roger Ebert for Beyond the Valley of the Dolls! All he did was write the first draft of the script. He’s not to be held responsible for the direction, the acting, the soundtrack, the costumes, the lighting, the editing, and maybe not even the dialogue; who knows how many rewrites there were.
The line isn’t “You’re going out a youngster, but you’re coming back a star!” It’s “You’re going out a youngster, but you’ve got to come back a star!” It’s not an acknowledgment of Ruby Keeler’s talent – it’s telling her that everyone is depending on her.
Bogart never said “Play it again, Sam.”
Cary Grant never said “Judy, Judy, Judy” in any movie. However, in Only Angels Have Wings, his ex-girlfriend was named “Judy,” and he said her name more than once. He also may have said it in a TV appearance with Judy Garland.
But in the “strange, but (apparently) true” department, she was hit in the head by a chunk of lead pipe when the group was loafing in St. Thomas, VI (before they were famous); she claimed that thereafter she could hit the high notes she couldn’t hit before.
Unless, of course, this has been debunked in some fashion.
I missed the bunny reference myself, but Lupe Velez, aka The Mexican Spitfire, was a star of the 40s. She killed herself with an overdose of Secanol, but He Who Shall Not Be Named Lest The Wrath of Eve Be Invoked, in his book Hollywood Babylon, popularized the falsehood that she awoke from her pill-induced stupor because of a heavy Mexican dinner she’d eaten prior to taking the pills, staggered to the bathroom to vomit and drowned in the toilet. Didn’t happen, although it did give birth to the funny Simpsons line “and that’s the hardware store where Lupe Velez bought the toilet she drowned in.”
