Julia Phillips' famous autobiography was titled, You' ll Never Eat Lunch in This Town Again.Barry Levinson and Art Linson will. At this point, if you're going to make a film about Hollywood greed, hypocrisy and lust, you have to be willing to burn your bridges. There's not a whole lot in "What Just Happened?" that would be out of place in a good "SNL" skit. Linson is an A-list producer ("Fight Club," "Into the Wild") who wrote this screenplay based on his memoir, subtitled Bitter Hollywood Tales From the Front Line. He knows where the bodies are buried and who buried them, but he doesn't dig anybody up or turn anybody in. If you want to see a movie that Rips the Lid Off Tinseltown, just go ahead and watch Robert Altman's "The Player" (1992). Altman took no hostages. He didn't give a damn. And the book and screenplay he started with were by Michael Tolkin, who was closer to the front line and a lot more bitter. He didn't give a damn, either.
