John Cleese will play a "significant part" in the upcoming 'Justice League' movie.
The 'Fawlty Towers' legend fuelled speculation he was joining the DC Extended Universe when he followed Ben Affleck - who plays Batman - and director Zack Snyder on Twitter, and was followed back by 'Batman v Superman's UK Twitter profile.
And now insiders have confirmed the 77-year-old star will be appearing in the ensemble blockbuster, which will see superheroes Batman, Superman (Henry Cavill), Wonder Woman (Gal Gadot), the Flash (Ezra Miller), Aquaman (Jason Momoa) and Cyborg (Ray Fisher) join forces to take down the evil Steppenwolf (Ciarán Hinds).
A source told The Sun newspaper: "Fans have speculated that he'd be a great addition to the film for a while.
"He's very versatile and can turn his hand to almost anything so no doubt he'll be great.
"The exact details of the role are being kept under wraps for now, but he'll have a significant part."
Last week, John shared a photo on Twitter of himself preparing for an event with copies of comic books 'Batman: The Dark Knight Returns', 'Justice League: Origin' and 'Batman Noir: Black Mirror' clearly visible.
He captioned the photo: "Getting into character before tonight's Q&A in Worcester, MA."
Meanwhile, filmmaker Zack recently spoke of how much he has enjoyed working on 'Justice League' because it features so many "fresh" characters.
He said: "These guys - Aquaman, Cyborg, Flash - really are just fun to explore. They're just so fresh. They're on the edge of their powers at different times in this story and that's really fun."
'Justice League' is expected to hit theatres in November 2017.
