Solidifying this theory, the Benedict Cumberbatch character is already set to make his first Marvel supporting appearance in the upcoming Thor: Ragnarok, and there’s also every possibility that Ant-Man and his crew will meet Doctor Strange during the events of The Avengers: Infinity War (which will be in production concurrently with Ant-Man And The Wasp).
With the connection between Doctor Strange and Ant-Man officially solidifying here, it forces us to ask a question: could this connection be furthered in Peyton Reed’s 2018 film Ant-Man And The Wasp?
We learn in Ant-Man that Hank Pym’s wife/Hope Van Dyne’s mother, Janet Van Dyne, has spent decades trapped in the Quantum Realm, and it’s possible that Dr. Stephen Strange could be very useful in rescue efforts.
