BOULDER, Colorado (KUSA) -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.

Twelve people died and 58 were hurt.
