George Clooney, Brad Pitt, Angelina Jolie and other red-carpet veterans joined some Hollywood newcomers in the Southern California desert this weekend to kick off the two-month-long movie award season at the Palm Springs International Film Festival. “When you're of age: drink,” Clooney noted to the newcomers at Saturday night's gala awards ceremony. “That's good advice to pretty much anybody.” Among those relative newcomers were Clooney's co-stars from the drama “The Descendants.” ‘'It is the first time we have dressed up all season,” said actor Matthew Lillard. “We have a couple months to put on nice dresses and suits.” __
