A recent rumor from Daniel Richtman via The Direct indicates the Joker is slated to make an appearance in Matt Reeves’ “The Batman” trilogy. At this time its unknown whether Joker will appear in the second or third film or possibly be a recurring villain. We do know however Joker is NOT going to appear in the first film and will only be referenced to in the first film.
Among these rumors are another that WB is currently considering Bane to appear in the sequels as well as the Joker. WB has reportedly passed on a Bane solo film however. All are still smoke and mirrors as the film is only 25% complete due to Corona virus shutdowns but the film now has the U.K’s blessing to resume filming.
