Matt Damon put on a big smile as he was greeted by fans to catch a flight out of LAX last night. Matt was accompanied by his wife, Luciana, for his happy travels out of LA. Matt and Luciana may be headed to the East Coast, since they're expected to join Channing Tatum, Jamie Foxx, and Maggie Gyllenhaal at the premiere of White House Down in NYC tonight. Matt will soon have his own red carpets to take care of since his new film, Elysium, is due out in the US on Aug. 9. Matt is back in the US after joining his good friend George Clooney overseas to shoot scenes for their upcoming collaboration, The Monuments Men. Matt and George were in uniform together on the set in England back in May.
