The Canadian actor is currently filming the movie, "Awake," in New York with Jessica Alba.
He was leaving his trailer the other day when he was approached by what appeared to be a fan seeking an autograph, the New York Post reported Tuesday.
But instead of asking for his John Hancock, the "fan" yelled at the actor: "You ruined the 'Star Wars' movies!"
A source on the set told the Post Christensen "chased the guy down the street and scared him away."
A spokeswoman for the Weinstein Co., which is producing "Awake," declined comment.
