Epic New 'Thor: Ragnarok' Trailer Reveals Just How Long Bruce Banner Has Stayed the Hulk

By
Get ready for an epic fight in Asgard!
The official trailer for Thor: Ragnarok was unveiled on Saturday during the Marvel panel at San Diego Comic-Con -- and it's a feast for the eyes!
The latest sneak peek begins with Thor (Chris Hemsworth) explaining that he lost his hammer and went on a "journey of self-discovery" until he reunited with his old pal, the Incredible Hulk/Bruce Banner, played by Mark Ruffalo. The two reunite after the events of Avengers: Age of Ultron -- and four years after what happened in the 2013 film Thor: The Dark World -- to defeat the villainous Hela (Cate Blanchett), though they'll need some help!
This time, Thor and his former nemesis/adoptive brother Loki (Tom Hiddleston) will work together, along with newcomer Valkyrie (Tessa Thompson), to take down Hela and save the people of Asgard.
During the star-studded Marvel panel, a new Thor poster was unveiled, and it was announced that Michelle Pfeiffer is joining the cast of Ant-Man and the Wasp, and that Brie Larson's Captain Marvel will take place in the '90s.
