Jake Gyllenhaal has been known to date some of entertainment's biggest female stars, including Reese Witherspoon, Kirsten Dunst, and Taylor Swift, but he's better known for his part in 'Brokeback Mountain' than anything else he's ever done in his life or career. He already had a great reputation in the movie world before this film, but the part hugely enhanced his status.
The relationship on screen between himself and Heath Ledger was utterly captivating and convincing. Gyllenhaal became conflicted rancher Jack Twist before our eyes and showed us every flickering second of his character's doubts and torments. The bond between the two men grew so strong in real life that Gyllenhaal went on to become the real-life godfather to Ledger's daughter! The ole won Gyllenhaal an Oscar nomination, and many believe he should have gone home with the award.
