Four big movies are opening this week. There’s a comic clash of cultures “Our Family Wedding” when “Ugly Betty’s” America Ferrara and “House of Payne’s” Lance Gross fall in love. “Twilight’s” Robert Pattinson and “Lost’s” Emilie de Ravin play characters who are both dealing with tragic loss who try to find solace in each other in “Remember Me.” “She’s Out of My League” is an outrageously raunchy comedy with Jay Baruchel (“Tropic Thunder”) as an airport security guy who falls for a dazzling girl (Alice Eve) and finds his biggest obstacle is his own insecurity (closely followed by learning to ignore the terrible advice of his friends). And in “The Green Zone,” Matt Damon reunites with Paul Greengrass, the director of the last two Bourne movies, for the fact-based story of an American officer who finds he cannot trust his intel about weapons of mass destruction and has to find out for himself.
