Marvel Studios is in a rather tough situation right now. While common sense says that the heroes who turned into dust will return in Avengers 4, they can't promote Spider-Man: Far From Home without potentially dropping some major spoilers and even the trailers for the Avengers: Infinity War sequel will need to go careful when it comes to showing off those who turned into dust after Thanos' snap.
One person who seemingly hasn't received the memo is Dave Bautista. In the interview below (which aired on national television in the UK), the actor casually confirmed that Drax will indeed return!
"We definitely see more Guardians in the upcoming Avengers, which we’ve already shot," he revealed. "Oddly enough, I guess I wasn’t supposed to say anything, but I was already saying before Avengers 3 was released that I’d already filmed 4, and I was signed up for Guardians 3. I’ve shot scenes for it, so I must come back somehow. It’s comforting but at the same time I felt a sense of guilt because I don’t know if I was supposed to say, and nobody told me not to say anything."
As the actor notes, he's already talked about working on Avengers 4 but the vast majority of moviegoers don't pay as much attention as us, so this is a pretty major spoiler to casually mention. It's interesting that he's also seemingly cooled on what he was saying about Disney; could it be that he's reconsidered his Drax future without James Gunn?
