“Brokeback Mountain,” like Annie Proulx’s short story of the same name from which it was adapted, revolves around Ennis Del Mar (Ledger) and Jack Twist (Gyllenhaal), two young men who fell in love while herding sheep in the summer of 1963. on the fictional Brokeback Mountain in Wyoming. For the next 20 years, the couple maintained a secret relationship with each other, even after they married women and had children. As you’d expect, their repressed emotions and desire to openly share their lives take a heavy toll on both of them, along with the rest of their lives.
Talking to Other Man Magazine in April 2020, Gyllenhaal recounted that Ledger helped him see how serious and tragic the story really is. As Gyllenhaal explains, the actor refused to perform a skit at the 2006 Oscars for fun:
“I was like, ‘Oh, okay… whatever.’ I always thought: it’s going to be fun, and Heath said, “That’s not a joke to me – I don’t want to make jokes about it.”
The success of “Brokeback Mountain” came as a surprise to Lee, who didn’t think many people would watch it due to its content. But even as the movie kicked in and the public began to treat its more famous dialogue as good lines (“I wish I knew how to give up on you”), Ledger remained unwavering. “That’s what I love about Heath. He would never joke,” Gyllenhaal told Sunday Today in 2019 (via Gay Times). “Someone wants to make jokes about the story or whatever, he says, ‘No. This is about love. Like that, man. Like, no.” This is how much concentration and attention hit a certain nerve. “
