The Batman is now out to the masses, and the DC Comics epic has undoubtedly left viewers with a lot to process.
Among a long-rumored member of the cast was Eternals and Dunkirk star Barry Keoghan, who was first publicly added to The Batman shortly after the project's first trailer dropped.
Months of speculation ensued about who Keoghan would be portraying in the film and fans definitely got their answer within the finished product.
In the film's final moments, The Riddler talks to an inmate in the Arkham prison who tried to calm Edward.
This is completely different from the role that Keoghan was initially reportedly cast as, with the initial official listing arguing that he was playing Stanley Merkel, a somewhat-recurring Gotham police officer.
In the months that followed, rumors began to swirl that he was really portraying The Joker but it is not.
Ultimately, Keoghan's appearance did make it through to The Batman as The Joker in the Arkham prison.
Opening a whole new can of worms as to how his story could unfold in future installments, whether that be the already-buzzed-about sequel to the film, or the number of spinoff series that are currently in the works for HBO Max.
