When Warner Bros. announced they would release this film with an R rating, making it both the first Warner Animation and first Batman-related film to not be rated PG-13 or lower, speculation mounted this was a response to the runaway success of the R-rated Deadpool (2016) film. However, the studio said that the reason for the R rating was that “Batman: The Killing Joke” was a violent, intense story that they did not want to water down, similarly to how they had been prepared to deal with an R rating for the earlier film Batman: The Dark Knight Returns, Part 1 (2012), before the MPAA gave it a PG-13 rating. Warner Bros. also felt it fit into the darker Batman universe after Batman v Superman: Dawn of Justice (2016), for which they released an R-rated Blu-ray and DVD version with thirty extra minutes of new, more violent material.
