The Dark Knight Rises star plays a Big Apple bike messenger in the fast-paced action movie, but he ran into a little trouble with a motorist after losing control of his bike on a busy road.
He tells BlogTalkRadio.com, "Early on in the shoot, probably day two or three, I was just warming up before we got our first shot and I was riding around without a brake which was silly. If you do that you should be a better cyclist. I got to be good but if you ride around without a brake you need to be very good, so that was foolhardy of me to be riding around without a brake. And I took off someone's side mirror!"
Gordon-Levitt admits the driver was initially furious, until the actor assured him production bosses would pay for the damage.
He says, "The guy was relatively cool about it; he was p**sed at first which was a little intimidating. I was apologetic and told him I was in the middle of shooting a movie and they (producers) will totally pay for your mirror. (I told him), 'Just tell them about it but I gotta go!' He came to the set and they paid for his mirror."
The smashed mirror wasn't Gordon-Levitt's only accident during the shoot - he needed 31 stitches to his arm after smashing through the rear windscreen of a taxi cab when a cycling stunt went awry.
