Actor Robert Pattinson was wracked with nerves while filming a gay sex scene for new Salvador Dali biopic Little Ashes - because the entire crew was watching, including a group of workmen.

The Twilight hunk portrays the Spanish surrealist artist in the forthcoming movie, but admits the toughest part of the job was having to strip off for the intimate tryst on an open set. He tells GQ magazine, "(The hardest part was) trying to do it doggie-style. Trying to have a nervous breakdown while doing it doggie-style. And it wasn't even a closed set. There were all these Spanish electricians giggling to themselves."

The project is one of three Dali biopics in the works. Al Pacino will play the artist in Dali & I: The Surrealist Story, while Antonio Banderas is set to star in another tribute film.
