“Brokeback Mountain” put Jake Gyllenhaal on Hollywood’s radar. He discusses the impact of the film on his career in a sneak peek at his upcoming interview with Willie Geist for “Sunday Today”.

“This is a level of focus and attention that hits a certain nerve,” Gyllenhaal says of the story of forbidden love between two male ranch hands. “This is bigger than me… It has become not ours anymore. It’s the world’s.

“That kind of attention, to be 26 years old, to be at the Academy Awards, you’re like, ‘Whoa.'”

Ultimately, says Gyllenhaal, the film “opened tons of doors. It was crazy. It was amazing. It’s defined my career in different ways.”

That was also true for co-star Heath Ledger. Gyllenhaal reveals Ledger would not permit any homophobic jokes about the movie and its famed line, “I wish I knew how to quit you.”

“I see people who have joked with me or criticized me about lines I say in that movie — and that’s the thing I loved about Heath,” Gyllenhaal tells Geist.

“He would never joke,” he explains. “Someone wanted to make a joke about the story or whatever, he was like, ‘No. This is about love.’ Like, that’s it, man. Like, no.”
