In a 2017 preview article on D23.com it was revealed that the Sorcerer Supreme himself, Doctor Strange, will be officially appearing in Thor: Ragnarok.
Here’s the direct quote on the subject:
“Thor: Ragnarok in November brings together Thor, the Hulk, and Doctor Strange to face off against intergalactic baddies both familiar and new.”
We already expected this based on the end of Doctor Strange, but it’s nice to have confirmation now.
With Hulk, Doctor Strange, and Thor, this movie will surely be a spectacle to rival other massive Marvel films.
Thor: Ragnarok hits theaters on November 3, 2017.
