Well, you'll be pleased to hear that JoBlo rumor was true: Mark Ruffalo will return as Bruce Banner and his slightly angrier alter ego in Thor: Ragnarok, which we recently found out would be directed by Taika Waititi (Eagle Vs Shark, What We Do In The Shadows).

Deadline just broke (well, confirmed) the news, though they don't mention any specific details or reveal how the Hulk will factor into the story - but Ruffalo and Chris Hemsworth seem like they have good chemistry, and their characters' interactions have provided some memorable moments in the Avengers movies so this should work out well.

Also starring Tom Hiddleston, Jaimie Alexander, Ray Stevenson, Anthony Hopkins, Thor: Ragnarok is currently being scripted by Christopher Yost and Craig Kyle and is scheduled to be released in theaters on November 3, 2017.
