Isla Fisher certainly looked the part of the sexy siren at the premiere of her new film The Lookout last night. Her fiance, Sacha Baron Cohen, was also on hand, but managed to elude photographers and let Isla shine on her big night. Rather than stay home and watch Dirt, Courteney was out on the red carpet too, perhaps the girls stayed in touch after the Borat premiere? Unfortunately it looks like the film's leading man, Joseph Gordon-Levitt, looks like he had a bit of an accident before the big night.

The thriller film stars Joseph as a mentally impaired janitor who is sucked into a bank heist. Isla plays his bad girl love interest, which is a little different than her hilarious character in Wedding Crashers, but we're sure she was up for the task.
