Warner Bros. made a minor edit to Aquaman in order to receive a lower rating for the film in the UK.
Much like the Motion Picture Association of America, the British Board of Film Classification is responsible for rating each film released in the territory. According to Digital Spy, when Warner Bros. originally sought advice from the BBFC about the film's potential rating, they were told Aquaman would likely be classified 15, a rating that means the film is suitable for people 15 years and over.
However, Warner Bros. was hoping for 12A, a rating that means the film is suitable for people 12 years and over. In order to get the desired rating, the filmmakers were advised to remove a "bloody detail." It seems they followed through on the suggestion, because -- when Aquaman was submitted to the BBFC for formal rating -- the detail in question had been removed. As a result, Aquaman was rated 12A by the BBFC.
It's not at all uncommon for a big franchise film to make small tweaks to get a desired rating, and the minor edit to Aquaman won't drastically alter the film. The BBFC's classification announcement also confirmed the film's running time of 143 minutes, approximately the same length as other DC movies centering on a single hero like Man of Steel and Wonder Woman.
Hitting theaters on Dec. 21, director James Wan's Aquaman stars Jason Momoa as Aquaman, Amber Heard as Mera, Patrick Wilson as Ocean Master, Willem Dafoe as Nuidis Vulko, Yahya Abdul-Mateen II as Black Manta, Temuera Morrison as Thomas Curry and Dolph Lundgren as Nereus.
