Anne Hathaway - Hathaway & Gyllenhaal Shared Sex Stories To Portray Lustful Couple

The Brokeback Mountain co-stars reunited for the film about a Viagra salesman and had to strip off to shoot a number of saucy scenes.

And to help them portray a lustful couple, the two actors discussed their own romantic histories and watched old movies to decide how best to film the intimate moments.

Hathaway tells Britain's Daily Mirror, "We had to go to a lot of emotionally and physically vulnerable places and we spent a lot of time rehearsing. We watched a lot of love scenes that have been done throughout film history and talked about which ones we liked and which ones we didn't.

"We talked about our own experiences with love and intimacy, about what turned us on and what didn't. So it was completely open from the get-go. Jake described it as a kind of intellectual orgy and I think that sums it up best."
