Law enforcement sources tell TMZ a woman called 911 after seeing what she thought were men on her roof with a rifle. When cops arrived, they found two young men, one with a camera and one with an unloaded rifle. From what we're hearing on the scene, the men are telling cops they are shooting a movie -- and NYU is nearby.
Both men are in cuffs and are still being interviewed at the scene.
It is not known if Hudson was home at the time.
