For now, Marvel is believed to only be shooting scenes for Doomsday, with the timing of Reynolds' post strongly suggesting he's set to return for that, rather than later down the line. Indeed, some fans are eagerly anticipating a second big reveal of Avengers: Doomsday cast members, perhaps via a second set of chairs, as production continues.

A cryptic new Instagram post from Ryan Reynolds has fans speculating that the actor could be returning as Deadpool in "Avengers: Doomsday."

Hopefully 'Avengers: Doomsday' does like 'X-Men '97' and lets Cyclops be cool and right when he's on screen. To celebrate Spider-Man Day, Tom Holland has shown off his new suit for 2026's 'Spider-Man: Brand New Day.' The president of Marvel Studios talks about the Fantastic Four's role in the upcoming Avengers film.
