Jake Gyllenhaal may be of Swedish descent, but his inner chef is definitely French, his costar in Source Code tells PEOPLE.
“Jake’s an incredible impersonator with great accents,” Michelle Monaghan said at the film’s world premiere at the South By Southwest Film Festival in Austin, Texas, this weekend. “We shot in Montreal, and [off-set] Jake played this sort of old, funny, French foodie chef – and talked a lot about food, because we ate a lot there.”
Monaghan, who plays a woman Gyllenhaal is trying to save in the sci-fi thriller about a man who occupies other people’s bodies for the final minutes of their lives, says she had a lot of fun with her costar – despite the serious nature of the film.
