CALGARY - There was a shocking twist to an afternoon showing of Watchmen yesterday afternoon after police used a Taser to subdue an unruly moviegoer.

Cops were called to the Scotiabank Theatre Chinook about 5 p.m. after a man -- believed to be in his mid-20s -- started causing a scene.

An employee, who asked not to be named, said the man looked "really drunk" and started yelling during the movie, prompting the manager to ask him to leave.

"He was drunk out of his mind," he said of the man.

"He was screaming."

Instead of leaving, the man pulled a four-inch knife on the manager and threatened him with it. Security was called, followed by police, who were also threatened with the knife.

Officers used a Taser to subdue the man, who was later taken to hospital.

"He was very, very drunk, so we're just waiting until he's sober," said Calgary police Insp. Keith Pollock.
