Jake Gyllenhaal is scared of ostriches.

His 'Prince of Persia: Sands of Time' co-star Gemma Arterton has revealed the Oscar nominated actor - who plays lead character Prince Dastan - was left terrified after being chased by the huge flightless birds in one scene in the Disney film.

Speaking at the world premiere of the action adventure movie at the Vue cinema in London's Westfield shopping centre, the 24-year-old actress - who plays Princess Tamina - told BANG Showbiz: "Jake is scared of ostriches. He ran away and the look on his face is not acting, it's real!"

Jake's fellow co-star Richard Coyle - who portrays Prince Tus - praised the 29-year-old star for coping with the movie's various stunts and action sequences.

He said: "You know... he was really good. He was lovely, brilliant. He had a lot to do and he did it well. He was brilliant. Magnificent."

As well as the movie's big names, other stars on the red carpet for the Mike Newell-directed film included Paloma Faith, The Saturdays star Una Healy and TV personality Kerry Katona.

'Prince of Persia: Sands of Time' - which is based on the computer game of the same name - is released on May 28.
