Gemma Arterton fell down a hill while making 'Prince of Persia: The Sands of Time'.

The British actress - who plays mysterious Princess Tamina in the Jerry Bruckheimer-produced epic - confesses nerves got the best of her when she first began shooting on the film and she tripped over.

She said: "The cameras are on me and suddenly I go out of the shot because I've fallen down the hill. I was mortified."

The 24-year-old star also believes the adventure movie will appeal to more people than 'Sex And The City 2', which is out on the same day, because Jake Gyllenhaal stars as lead character Prince Dastan.

She told E! Online: "You should see my movie because it's got Jake Gyllenhaal in it. There are no really hot guys in 'Sex and the City'. There's amazing outfits, but in 'Prince of Persia', there's a lot of male testosterone, which is quite sexy."

Despite her competitive streak, Gemma is a fan of 'Sex and the City', which stars Sarah Jessica Parker.

She said: "I love 'Sex and the City'. Even today, there was something on TV about it, and there was a silent yelp inside of me."

Gemma has starred in a slew of films so far this year, including 'The Disappearance of Alice Creed' and 'Clash of the Titans'.
