Jake Gyllenhaal thinks ostriches are scarier than wolves.

The 29-year-old actor - who had to take part in a number of stunts while shooting 'Prince of Persia: The Sands of Time' - was happy getting involved in the action, but didn't want to go near the large birds.

He told USA Today newspaper: "The scariest scene is when Alfred Molina kisses an ostrich. They are terrifying animals. Anything with a brain the size of a pea and claws that can tear your face apart is really scary.

"I've worked with wolves in movies on 'The Day After Tomorrow', and on this set they treated ostriches like wolves. They literally told us they've been known to rip off people's faces. So when Fred kisses the ostrich, to me that performance is braver than Robert De Niro in Raging Bull."

However, Jake added that the prospect of some stunts in the movie were enough to scare even professional stuntmen.

He said: "There's a jump I do where there's like a 20-foot gap between two buildings and a pretty significant drop, like 35 feet, which terrified even the stunt guys."
