Jake Gyllenhaal Tongue-Tied Meeting Tom Cruise

Even movie stars get starstruck around other movie stars.

Actor Jake Gyllenhaal tells "Extra" at the premiere of his action flick, "Prince of Persia," that he "didn't know what to say" to Tom Cruise when they were together honoring producer Jerry Bruckheimer, who received a star on Hollywood Blvd. this week.

Gyllenhaal confesses, "[Tom] was like 'How ya doin', man!' And I was like, uh-uh-uh."

What about the story that Gyllenhaal was scared of the ostriches chasing him in a scene from "Persia." "Anything with the brain the size of a pea, that can tear your face out is terrifying. Use that!"
