Jake Gyllenhaal landed in Toronto on Saturday, going incognito in a Yankees baseball cap, before heading straight to work in the Canadian city on Sunday. The scruffy actor has been up north filming his upcoming An Enemy, which costars French actress Melanie Laurent, in between visits home to NYC. On Sunday, Jake sported a leather jacket and motorcycle helmet to shoot scenes in the city streets. The movie features Jake as a teacher who discovers a man who looks just like him living nearby, and was inspired by the classic Dostoevsky book The Double. In fact, Jake looked to be playing a different character on Sunday than he was last week. Last Tuesday, he was on set in a straight-laced suit, but this weekend he looked a bit more bad-boy in his leather jacket, with a cigarette in hand.
