Last year, American film producer and Marvel Studios President, Kevin Feige, hinted a connection between the movies Ant-Man that stars Paul Rudd and the forthcoming Doctor Strange. Feige has told EW that, "scratching the surface of the Marvel mind trip, the mind-bending natures of reality, which is something that we're going to completely go off the rails with in Doctor Strange."
In review, it looks like Feige was discussing about the Quantum Realm, the subatomic dimension Paul Rudd's tiny superhero Scott Lang visits in Ant-Man and, and according the Marvel Studios President, is a sign of things to look out for in the upcoming Doctor Strange movie, which casts Benedict Cumberbatch as the titular sorcerer, which will be released on Nov. 4, 201.
EW has reached out to to Ant-Man filmmaker Peyton Reed and got this answer, "There may well be a link between the Quantum Realm and alternate realities and parallel universes and Doctor Strange. The definite link is that psychedelic era of the Marvel comics world - the late '60s, early '70s stuff."
Looks like the Ant-Man filmmaker Peyton Reed did not want to spill any beans just yet.
"It was something that Adam McKay (Ant-Man cowriter) and I really wanted to bring to the Ant-Man movie," Reed added. "We knew that there was going to be a lot of shrinking in the movie, but we wanted to take it even further in the third act. There's a lot going on in the Quantum Realm and there's a lot of storytelling possibilities. The fact that Scott survives the Quantum Realm in the movie - which Hank Pym said is theoretically impossible - got Hank Pym spinning again, wondering about, 'Is there a possibility where my wife might be still alive down there?' So it may have set off this obsession again. It remains to be seen if that's a good thing or a bad thing."
