spokesperson has confirmed that the broadcast cable version of Birds of Prey was "mistakenly added to the service," and that "the unedited original version will be available on HBO Max instead.".
The HBO Max version of Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn) has apparently been censored from the original version that was found on the streamer and in theaters.
As reported by ComicBook.com, HBO Max subscribers that start the DC film are greeted with a message saying, "This film has been modified as follows from its original version: it has been edited for content.".
ComicBook.com also writes that this wasn't the first time a streamer has offered a "tamer version of the film," as Netflix had the TV edit of Back to the Future II for a while before it was corrected.
