Ninjas are known for being the most silent of killers, so it’s particularly apt that one London movie theater is sending them to take care of noisy movie goers. The Prince Charles Cinema in Leicester Square is now employing ninjas who sit in on movies and make sure everyone behaves. If you’re chatting, throwing popcorn or texting during the movie, then these ninjas will ask you to settle down. They’re technically not ninjas, but they are guys clad in skintight, full-body zentai suits. Close enough. I kind of want to go to this theater and behave badly just to see what they’ll do.
