Pattinson is an unexpected choice to replace Affleck. He shot to stardom in vampire-romance franchise Twilight, which saw him star as brooding teen vamp Edward Cullen across five hit films.
More recently, he's starred in The Lighthouse, which premiered at Cannes Film Festival, Claire Denis' High Life, Netflix's Waiting for the Barbarians, and is currently starring in Christopher Nolan's latest offering, Tenet.
According to Deadline, Tolkein star Nicholas Hoult was also on a short list for the role.
Armie Hammer and Aaron Taylor-Johnson have also previously eyed the role, which has been held in the past by the likes of Christian Bale and George Clooney.
