The funny man was NOT in the mood to be filmed!

James Franco attended rumored girlfriend Lana Del Rey's concert at the Hollywood Forever Cemetary over the weekend, and the actor ended up getting frustrated with a photographer and knocking him over in an attempt to get away. When the photog told the Pineapple Express star what he had done, the A-lister blamed his aggressive maneuver on his inability to see because of the blinding video camera light.

"F**k off!" the quirky star told the camera man as he made his way out of the venue. It's weird because he goes back and forth between sounding somewhat remorseful and trying to explain himself, to being downright furious and dismissive of the whole incident.

Don't mess with him!
