'Source Code': Watch a confused Jake Gyllenhaal in the movie's first five minutes, now online

No longer sporting his lush "Prince of Persia" locks, a neatly-shorn Jake Gyllenhaal plays a helicopter pilot who wakes up in some other dude's body on a train that is just minutes away from being engulfed by an outsized CGI-assisted fireball from hell in "Source Code."

Since the first five minutes of the movie -- which opens April 1 -- are now conveniently available online, watch as Gyllenhaal delivers a passably confused performance opposite Michelle Monaghan. We were hoping the rabbit from "Donnie Darko" would make a cameo appearance, but alas, no such luck.
