“Minions: The Rise of Gru” is one of the biggest movies of the summer, setting a new record last week for box office sales over Fourth of July weekend at about $125 million.

But that success has come with some unwanted consequences as a recent TikTok trend has led hoards of teenagers and young adults to theaters in full Minion costumes, where some have caused damages and disrupted showings for other viewers.

And the trend has already made its way to Dartmouth.

“I’ve had to remove a few kids,” said DJ Olson, the manager of the AMC theater located at the Dartmouth Mall.

Olson said that while most theater goers have been respectful, the staff have made it clear to anyone appearing in costume that being disruptive or recording videos in the theater will not be tolerated.

He said the staff has made extra rounds in theaters showing the movie, “to let them know we’re there.”

“If you’re here to enjoy the movie, that’s cool,” he said. “But if you’re here to wreck it for other people, we’re going to ask you to leave.”

Olson added that the theater was fortunate to have not only its own security, but mall security and a nearby police station to call on if things get really out of hand.

AMC corporate, Olson said, has sent emails to the branch warning that some of the Minions fans have gone so far as to set off fireworks inside the theater.

Though nothing like that has happened in Dartmouth, the AMC has welcomed several large groups of costumed viewers, and have had a few strange incidents.

In one case, theater workers found a pile of abandoned clothes, leading to some worrisome speculation.

“We had one guy undress in the lobby,” said Olson. “There’s a lot of weird things you find in a movie theater, but a pile of clothes is a bad sign.”

Luckily, Olson said, the owner of the clothes was later found wearing a different outfit.
