Actress Anne Hathaway had a crash course in horse riding before filming began on Brokeback Mountain after she deceived movie-maker Ang Lee into thinking she was an equestrian expert.

When the director asked THE PRINCESS DIARIES star if she had any experience on horseback she joked about her riding skills - and he took her seriously.

Hathaway says, "Ang actually asked me if I had ever been on horses during the audition and I just told a bold-faced lie and said something like 'Of course, I'm an Olympic jumper!'

"So I actually had to learn how to ride a horse - in Central Park (New York City)."
