A lot of the stars on this list took a course directly related to their field of interest, or even something that went hand in hand with a career they'd already started. Maggie Gyllenhaal took a different route. Although she'd already started to build a career in TV and film by the time university rolled around, she actually put that career on hold and tried something completely different. Specifically, she went to Columbia to study literature and Eastern religions. She would have been there at the same time as Julia Stiles, although it's unclear whether they ever met.
The studies presumably complemented her complex and diverse background - she's from a Swedish-English ancestry and identifies as part Jewish and part Swedenborgian when it comes to spirituality. She topped off her studies by attending London's prestigious Royal Academy of Dramatic Art before resuming her career.
