Jake Gyllenhaal was back on the set of Source Code yesterday in Montreal and showing off his moves while rehearsing for a fight scene. He's been in Canada for about a week after filming in Chicago for a few days with costar Michelle Monaghan. Jake's enjoyed a little downtime despite his busy work schedule, and even brought his mother out for a special brunch on Sunday. He apparently made the big step of introducing Isabel Lucas to his mom, but Jake seems to be taking it easy in the romance department after telling GQ that he's not sure about finding the right woman at this particular moment.
