On a warm Southern California evening, director Paul Thomas Anderson got right to the point for the Los Angeles premiere of Warner Bros.’ “Inherent Vice” at the Egyptian on Saturday.

He started to intro the cast, changed his mind, praised the Egyptian and said, “It’s a good Saturday night movie.”

On the red carpet, Josh Brolin admitted that he enjoyed the low-key atmosphere of the AFI Fest — “This is the most relaxed red carpet ever” — and said the first film adaptation of a Thomas Pynchon novel evoked a unique reaction every time he’s seen it, much like listening to Tom Waits.

Brolin asserted that acting with Joaquin Phoenix raised the stakes for him during the shoot and that he was only to relax after completing a scene. He also allowed that he’s still insecure about all his roles.

Attendees exited the Egyptian at mid-evening and walked to the post-screening bash at the Hotel Roosevelt. A common comment was “I’m going to have to see it again so I can understand what happened.”

“Inherent Vice,” the first movie to be based on a Thomas Pynchon novel, is set in Los Angeles in 1971. Warner Bros. opens the film on Dec. 12.
