Matthew McConaughey donned a cowboy hat and boots for an appearance at the LA Film Festival alongside Camila Alves last night. The duo were there for the premiere of Matthew's indie movie, Bernie, which also stars Jack Black and Shirley McLaine. The dark comedy opened the festivities and was screened just before Ryan Reynolds's Green Lantern. MM and Camila enjoyed their adults-only evening after spending Wednesday at Disneyland with Levi and Vida. Their adorable family caused quite a stir at the amusement park, though they were a little more low key during a recent trip to their Santa Monica church.
