Jake Gyllenhaal was determined to do as many stunts as possible in 'Prince of Persia: The Sands of Time'.

The 29-year-old actor got into phenomenal shape for his action-packed role as Prince Dastan in the movie and really enjoyed the physical challenges of the project.

Jake - who practiced the French discipline of parkour, which involves leaping over city obstacles, to help him get fit - he told The Independent newspaper: "I really wanted to see if I could do this. I wanted to try my hand at it. I took a photo of myself after one big 35ft jump. I was pretty nervous. I put on the harness and looked over The Edge about five times. After I did it I took a photo, I felt so proud."

Jake has previously admitted he took his training for the film very seriously because he didn't want to let down director Mike Newell and producer Jerry Bruckheimer, who is known for his thrill-a-minute action films.

He said: "It was really important for me to be able to do all the stunts and the things asked of me."
