Owen "Attacks" Extra

Looks like Owen Wilson is getting camera shy both on and off the set. Just days after we reported that the fragile funnyman went balistic on a party photog, the 39-year-old lunged at an extra on the set of his new flick Marley & Me.

A PageSix.com spy said Owen acted like a royal "jerk" on Thursday when "he saw an extra taking a picture of him with a camera phone. He rushed up to him and the guy next to him and snapped 'Are you guys taking pictures of me?'"

The insider said Owen — who's on set daily with co-stars Jennifer Aniston and Eric Dane — makes his security guard keep everyone away from him and is always "just out of the camera's view during action shots."

"No one on set can approach [Owen] because of his security but he can run up and attack extras about taking a picture." Owen's rep didn't return an email request for comment by time of publication.
