Mark Ruffalo will be smashing his way back onto the big screen in Thor: Ragnarok. The third solo Thor film will apparently involve both Hulk and the Norse god on a distant planet. The Hulk was last seen in Avengers: Age of Ultron, when his human form Bruce Banner went off in exile to protect humanity from the green beast. Thor: Ragnarok will bring back Chris Hemsworth as the titular hero, while Jaimie Alexander returns as Lady Sif. Tom Hiddleston has been coy on when he'll next play Thor's twisted brother Loki - although he will reportedly feature in Ragnarok.
