Gemma Arterton isn't enough of a "sex goddess" to please fans of the 'Prince of Persia: The Sands Of Time' computer game.

The British actress has been told by fans of the computer game - which her latest film is based on - she doesn't meet their expectations for her character, Princess Tamina, leaving her scared to go to a comic convention to promote the film.

Gemma said: "They want me to go to Comic-Con. It kind of worries me. I've had letters telling me I'm not right for the part because I don't look like the girl in the video game!

"She really is this sex goddess. They've got massively high standards."

Gemma's character's name was changed from Farah to Tamina for the 'Prince Of Persia: The Sands of Time' film, in which she stars alongside Jake Gyllenhaal, who plays the lead character Prince Dalston. The film is an adaptation of a 2003 computer game of the same name and sees the prince and princess trying to prevent an epic sandstorm swallowing their homeland.

Despite Gemma's Hollywood career taking off - with a role in 'Clash Of the Titans' and having previously appeared as one of the women seduced by the British spy character James Bond in 'Quantum of Solace'- she also appears in low budget thriller film 'The Disappearance of Alice Creed', a film she wholeheartedly believed in enough to appear naked.

She added to Details magazine: "This is the sort of movie I always imagined I'd end up doing. This is the sort of movie I'd go to see in the cinema.

"I wouldn't get my clothes off for just any film. On camera I really didn't give a s**t, but as soon as they said 'Cut!' I was like, 'Someone put the dressing gown over me!'"
