Hulk Rumored For Thor 3
It was thought the Green Goliath would be appearing in Captain America: Civil War; however, that doesn't seem to be the case.
So where will we see Banner next?
According to the report, Thor will team with the Hulk as Asgard faces a Norse Apocalypse.
The report further mentions that Tom Hiddleston will be back as Loki, as there seemed question as of late if Hiddleston was set to return; Jaimie Alexander is also said to be back as Sif.
It's also said a “distant planet” is involved in Thor 3 that is "not Asgard and not Earth" which is speculated to possibly be the planet Sakaar where the Planet Hulk Marvel Comics storyline took place.
Regarding Mark Ruffalo, the actor is said to be absolutely part of the supporting cast of Thor 3 and will be featured prominently as Banner.
Thor: Ragnarok has a November 3, 2017 release.
