The filming of "Superman Returns" had to be halted after thieves stole a batch of walkie-talkies and went about impersonating crew members.

According to the Internet Movie Database, the jokers went about the set saying "Cut" and "Action" on the walkie-talkies forcing filming to be temporarily suspended. The joke could have gone too far as the crew were filming an action sequence involving a car speeding down steps and landing between a group of extras.

The news of the robbery was not reported to police. A source says, "That film's got so much money, a couple of missing walkie-talkies wouldn't worry them."
