19Probably Leaving: Dave Bautista
Dave Bautista gave a star-making performance as Drax in the Guardians of the Galaxy films, as well as Avengers: Infinity War. The former professional wrestler proved his worth as an action star. More than that, though, he displayed an ace sense of comic timing that allowed Drax to steal scenes
from every other Guardian.
By his own admission, Bautista would love to continue playing the character. However, he has publicly stated that he won't reprise the role for any future Guardians of the Galaxy sequels unless Disney re-hires James Gunn, who was fired after a controversy involving some old Tweets. Disney has refused to bring Gunn back into the fold, and the director has reportedly moved on to other projects. Therefore, Bautista is very possibly done with the MCU after Endgame.
