Mark Ruffalo's Hulk will appear in Thor: Ragnarok

Confirming rumors that surfaced earlier this week, Mark Ruffalo is in final negotiations to appear opposite Chris Hemsworth in Thor: Ragnarok, reports Variety. It will mark the first time Ruffalo has portrayed the character outside of an Avengers film.

JoBlo initially reported the rumor, which Variety has confirmed through its own sources. Tom Hiddleston and Jamie Alexander are expected to reprise their roles as Loki and Sif, with the character Valkyrie rumored to make her debut in the Marvel Cinematic universe.

Little is known about the plot of the film, other than that it takes place somewhere other than Earth or Asgard. But its subtitle, Ragnarok, seems like a pretty big hint. There's also no knowing exactly how the Hulk will become involved, as the last time we saw him he was fleeing the Avengers in a stolen craft that was eventually found crashed and abandoned.

However, the Hulk has had some memorable space adventures in the comics, most famously the foundations for the World War Hulk storyline. That particular arc involved a scheme to send the Hulk into space where he wouldn't hurt anyone that lead to him becoming a gladiator on another planet, then the leader of a revolt on that planet, and then the ruler of that planet, before eventually returning to Earth for revenge.

Look, sometimes Reed Richards has ideas that don't pan out all the way.

Thor: Ragnarok will be directed by Taika Waititi, from a script by Christopher Yost and Craig Kyle. It will hit theaters on Nov. 3, 2017.
