There are only a few clues to our disposal to figure out what Avengers 4 might be about. "Ant-Man And The Wasp" also featured Rudd as Lang and Evangeline Lilly as Van Dyne, alongside Michael Peña, Walton Goggins, Bobby Cannavale, Judy Greer, Tip "T.I".
Now, if you've watched Infinity War as many times as we have, you'll know that there wasn't much chat from Doctor Strange about Quantum Realms or Quantum tunnels. "Ant-Man And The Wasp witnessed ample growth on Saturday".
"He has the most hard lines though", Holland said about Cumberbatch, who plays Doctor Strange.
"He (Cumberbatch) has to talk about so much Quantum Realm stuff". Two factors can help the film record high occupancy over the weekend in multiplexes; it is an action film and stars Tom Cruise in lead. This little leak all but confirms some fan theories of the Quantum Realm being the key to taking down Thanos and being the anchor for the still untitled Avengers 4. "I just have to talk about, 'Yeah, man, that's awesome!' So mine is easy but his is so hard!" Before Ant-Man enters it, Hope warns that if he gets trapped in a time vortex, they won't be able to save him. In a new interview, Cumberbatch reveals that he loved the ending of Infinity War and that he was "thrilled" by the pitch for Avengers 4, which makes us believe that he'll be back.
This also brings in the multiverse theory and opens to doors to almost endless possibilities for the future of the MCU.
So the events of "Avengers 4" influenced the making of that scene. Before getting "snapped", unusual views millions of different possible outcomes for the battle with Thanos, and in only one do the Avengers prevail. The theory goes on to predict that unusual actually took a Time Stone from the future, a future where the Avengers defeated Thanos, which is why the snap did so much damage to the Infinity Gauntlet. Only in this one case was he entangled in the Quantum Realm and is now the person who can save the day via this Realm.
We'll have to wait until next year to see if this all plays out how fans are guessing, but in the meantime, maybe Holland will strike again.
