Sorry, moviegoers: If you’re going to see 50 Shades of Grey on opening night next Friday in costume, you’ll have to leave your ties and whips at home.

At least one theater chain is banning props and other accoutrement in their theaters. “We do not permit weapons, real or fake, or items that would make other guests feel uncomfortable or detract from the movie-going experience,” said AMC spokesman Ryan Noonan. “If someone tries to bring in a bow and arrow for the next Hunger Games, we’ll ask them to leave it in the car. If someone shows up in a Bane mask, we’ll ask them to remove it. If someone starts tossing around a whip or pulls out handcuffs, we’ll ask them to put it away. We think common sense will prevail.”

Noon stressed that this policy was not specifically in response to 50 Shades of Grey, but would apply to any movie screened at an AMC theater. AMC has more than 300 theaters and 4,000 screens across the country.

So remember: popcorn is allowed, handcuffs are not.
