As Todd Phillips' Joker nears its wide release and the discourse regarding the film's portrayal of violence continues, one movie theater has taken it upon itself to remind parents that the DC Comics-based character study is rated R. As such, it's probably a good idea to get a sitter and live the kids at home for this one.

Alamo Drafthouse Cinema Omaha has shared a PSA-esque Joker poster on its official Facebook page. The image -- which is an edit of the film's original teaser poster featuring Joaquin Phoenix as the Clown Prince of Crime -- highlights the reasons the film was given an R rating by the MPAA in the first place. The poster is accompanied by a simple caption, which reads, "FYI."

"Parental warning. (This is not a joke)," the poster itself reads. "Joker is rated R and for good reason. There's lots of very, very rough language, brutal violence and overall bad vibes. It's a gritty, dark and realistic, Taxi Driver-esque depiction of one man's descent into madness. It's not for kids, and they won't like it, anyway. (There's no Batman)."

Directed by Todd Phillips, Joker stars Joaquin Phoenix, Robert De Niro, Zazie Beetz, Bill Camp, Frances Conroy, Brett Cullen, Glenn Fleshler, Douglas Hodge, Marc Maron, Josh Pais and Shea Whigham. The film arrives in theaters Oct. 4.
