During an interview on The Late Show With Stephen Colbert on Oct 5, the star was asked if he could still fit in the suit, to which he replied: "Svelte as ever, man. Same dimensions, or same fitting." He continued to joke: "I don't know how many are there, like 77 Batmans? They think that they should probably form their own union."
Keaton is currently filming the highly anticipated DC Comics film The Flash, alongside Ezra Miller and fellow Batman, Ben Affleck, who were both recently seen together in Zack Synder's Justice League. It was confirmed that Keaton would be returning as the original Batman from the 1989 film. Fans have speculated that this will be possible through the concept of a multiverse, which will be explored in the film.
When asked if there was a place where all the Batman actors would meet, Keaton stated tongue-in-cheek: "I don't know ... not until the union is formed."
Other actors who have played Batman include George Clooney and Christian Bale. The next in line to play the caped crusader is Twilight star Robert Pattinson who will appear in Matt Reeve's The Batman. Unlike Keaton's depiction, Pattinson will portray the superhero during his early years of crime fighting.
The Batman will be released in March next year while The Flash will premiere in November 2022.
