Fans who have seen "Doctor Strange" (spoiler alert) would know that Chris Hemsworth appeared as a very casual-looking Thor in the mid-credits of the movie. During their encounter, Thor asked Doctor Strange's help to locate his father Odin as well as deal with his brother Loki.

According to official Disney fan club D23, Cumberbatch will join Hemsworth in "Thor: Ragnarok. "If you need even more intergalactic, world-saving action, Thor: Ragnarok in November brings together Thor, the Hulk, and Doctor Strange to face off against intergalactic baddies both familiar and new," the article read.

This does not exactly reveal much, but it is enough to confirm the Sorcerer Supreme's role in the film. Fans of the "Sherlock" star are very excited for his participation in the third "Thor" film, especially so if he shares a scene with Tom Hiddleston, who plays Loki. The British actors are very good friends in real life and their bromance has secured a legion of followers. Since both actors, and their respective characters, are insanely witty it will be an absolute thrill to see their exchanges on screen.

Meanwhile, the official synopsis to "Thor: Ragnarok" has been released and it confirms one popular theory about the story. The synopsis details that Thor and Hulk will battle it out in a gladiator match.

"Thor is imprisoned on the other side of the universe without his mighty hammer and finds himself in a race against time to get back to Asgard to stop Ragnarok - the destruction of his homeworld and the end of Asgardian civilization - at the hands of an all-powerful new threat, the ruthless Hela," the synopsis reads, as quoted by The Hollywood Reporter. "But first he must survive a deadly gladiatorial contest that pits him against his former ally and fellow Avenger - the Incredible Hulk!"

"Thor: Ragnarok" will premiere in theaters on Nov. 3.
