D23 has posted what they're most excited to see in 2017, and not only do they confirm Doctor Strange is in Thor: Ragnarok but they also indicate that he as a sizable role in the movie.
"... 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..."
I mean we all figured this was the case given the mid-credits scene of Doctor Strange, but it's nice to finally have the confirmation. Benedict Cumberbatch's Sorcerer Supreme is definitely a hero that can fight along side the God of Thunder and the Hulk! Thoughts?
