Jake Gyllenhaal wasn`t allowed to get too muscular
The 29-year-old actor got into incredible shape for his action-packed role as Prince Dastan in the Disney movie but producer Jerry Bruckheimer kept the bodybuilding in check.
He said: "Of course I worked out a lot! But we always had to make sure not to overdo it. Jerry kept popping into the gym to check our muscles weren`t getting too big, because he didn`t want us to look too massive on screen. He said, `Always remember - no huge biceps!`
"For a whole month I did a lot of climbing and sword fighting."
Jake insists Jerry was a constant inspiration on set and has even made him consider becoming a movie producer himself.
The Hollywood heartthrob added to website Skip.at: "Seeing Jerry producing this film I just thought, `I want to do this as well!` He knows how to make the most complicated things look easy. And I love films more than anything - so it`s only logical for me to work behind the camera as well."
