MANHATTAN — The off-screen drama on one Upper West Side movie set might rival anything that makes it onto the big screen.
A frustrated pedestrian snapped when a movie staffer blocked his path near the set of Joseph Gordon-Levitt flick "Premium Rush" Saturday, head-butting the production assistant and venting a fury felt by many Manhattanites.
"I live here, I pay taxes," yelled Breffny Flynn, 43, who was on his way to buy paint when he was told to wait while filming was done on West 102nd Street and Broadway on Saturday, the New York Post reported.
"Don't tell me what to do, motherf--ker. I gotta get to the store, I gotta get to the store."
Flynn, who is 6-foot-4 and 285 pounds, left movie assistant Steve Lafferty with a bloodied nose.
