Camp: Camp Walt Whitman
J-Connection: The Los Angeles born actor’s first big role was in the cult classic “Donnie Darko,” although he and his equally talented sister Maggie have since gone on to star in numerous other hit films. Gyllenhaal’s mother is Jewish, and his bar mitzvah was held at a homeless shelter in order to give the teen a sense of how privileged he was.
