Jake Gyllenhaal has admitted he didn't enjoy filming new movie 'Brokeback Mountain.'

The heartthrob - who played a gay cowboy in the film - said he struggled to enjoy his time on set because of director Ang Lee's cold work manner. The actor and co-star Heath Ledger felt that as soon as shooting started they were given the cold shoulder by the movie mogul.

He explained: "Ang purposefully makes you feel a little uncomfortable. Yesterday, he said to me that he felt so good when making this movie, which is funny because Heath and I think it was really hard for us."

"I don't think 'good' would be the right way to say how we felt when we were making it."
