Teen wearing 'Joker' mask sparks panic inside Colorado movie theater

NBC NATIONAL NEWS — A late night movie turned terrifying for a group of Boulder, Colorado moviegoers when a teenager pulled a prank early Sunday morning.

Several people fled the theater in a panic when the 17 year old entered wearing a Joker mask, which immediately brought to mind accused theater shooter James Holmes.

Holmes dyed his hair and police say he called himself the joker at a midnight showing of the latest Batman movie on July 20.
