The controversial film ‘Joker’ has made its debut across the country, and it’s caused a bit of a ruckus.

Landmark Theater asked moviegoers nationwide to leave their costumes and masks at home if they’re going to see ‘Joker.’ AMC Theaters issued a similar warning. Since the Aurora, Colo. movie theater shooting in 2012 where the perpetrator dressed as The Joker, AMC placed a seven-year ban on masks and face paint.

Police departments in several cities including Chicago say they’re going to increase patrols at theaters showing the film.

A Chicago Police spokesperson says officers with theaters on their beat are being asked to pay special attention to them. They said they’ll check in with theaters regularly.

“I’m not worried at all. I figure if there’s somebody out there that wants to do harm to people, they’ll do it regardless anyway of what the movie is. So I’m not thinking about it at all. I just want to see a good movie,” moviegoer Joseph Joyce told CBS 2.

Some theaters are choosing not to show the movie at all. The Century 16 theater where the shooting happened in Aurora, Colo. will not play the movie.
