Vin Diesel has sometimes been known to jump the gun on announcing things. Case in point: when he recently teased the Fast 8 trailer's premiere date months in advance (he's predicting an Oscar win, too).
So it's not really surprising that the actor known for freewheeling interviews offered up some very premature information during a recent interview with Screen Junkies. Diesel was sitting down during Brazil Comic Con to promote his latest film, XxX: The Return of Xander Cage, when the interviewer asked him about the possibility of his tree character Groot from Marvel's Guardians of the Galaxy franchise appearing on screen alongside Spider-Man.
"That's an interesting question. I think if it's up to (Guardians of the Galaxy director) James Gunn, you're going to see a Groot and Rocket movie after Infinity Wars. That's highly possible. We shall see. ... I know that there's somewhere in the universe that you're gonna see Groot and Hulk battle, I know it."
Gunn, not surprisingly, hasn't responded publicly to the possibility of a spinoff starring Guardians' Groot and Rocket Raccoon, who's voiced by Bradley Cooper, but it's an interesting possibility. The "Infinity Wars" Diesel was talking about is Avengers: Infinity War, Part 1, which is confirmed to be featuring characters from Guardians of the Galaxy. As far as a Groot vs. Hulk throwdown, it has actually happened in the comic books, so it's not that crazy an idea.
The first teaser trailer for Guardians of the Galaxy: Vol. 2 was released two days ago, and quickly became the second biggest teaser of all time, according to Gunn himself.
