Avengers: Infinity War could be the most secret Marvel movie ever to hit the cinemas. The plot of the third Avengers movie is so top secret, only Doctor Strange star Benedict Cumberbatch has even admitted to reading the entire screenplay. Coincidentally, this recording has triggered a massive fan theory that time travel will be strong in the next two Avengers movies. And if you have not seen Doctor Strange you will wonder how the time travel Avengers: Infinity War works.
Time travel was never really big in the MCU. Yes, movies such as Iron Man 2 and Captain America: Civil War rely on flashbacks to make a complete narrative, and yes, the leap in time between Captain America: The First Avenger and The Winter Soldier feels like a journey through time. But time travel was never crucial for an MCU narrative until Doctor Strange which is why Doctor Strange's prominent role in some of the early trailers for Infinity War served as a signal for fans Time travel will be crucial for the movie.
In Doctor Strange the titular wizard receives an amulet, the Eye of Agamotto. The amulet contains the Timeline, one of the Infinity Stones that Thanos searches for in Infinity War and allows the wearer to manipulate time. The magical object is not easy to use, nor is it meant to be used often. Dealing with the space-time continuum is always difficult and involves countless risks. It's a last resort at best ̵
Granted, just because Doctor Strange in is Infinity War does not necessarily mean he uses the Timeline. He briefly appeared in Thor: Ragnarok and there was no time travel in this film. However, in a recent interview with Good Morning America Cumberbatch revealed that Doctor Strange would be at the center of Infinity Warfare after he admitted he had read the entire script co-stars insisted that they did not make it). "I had to somehow understand what the context was," said Cumberbatch. "Strange has this wonderful role in it and I'm trying to find the multiverse together, so somehow I had to know what's going on in between."
Assuming that Strange is crucial to Infinity War it makes sense that the film would involve time travel. At this point in the MCU, Doctor Strange, with no time travel, is almost like Thor without the power of thunder. Sure, both superheroes have other powers to keep them safe during a fight, but they're not known for that.
Doctor Strange's Eye of Agamotto aside, time travel could also be somewhat less literal when it comes to [19459003geht] Infinity War . As mentioned above, the MCU is strong on flashbacks, and it's just that Tony Stark has created a technology that connects the two. "Certainly in Civil War there is a five-minute sequence around a piece of technique that has been put in for a reason, so if you go back and watch the movie, you can point to one direction," said Co-director Joe Russo opposite Josh Horowitz about Collider. As Collider reports, it seems that Russo is talking about Tony's Binary Augmented Retro Framing, the technician who revived his last memory of his parents in the inauguration of Civil War . It is possible that this device will be used by the Avengers somehow in Infinity War and will replace the actual time travel.
If time travel in Infinity War is not strong, it might well play a big role in Avengers 4 . Some fans have hypothesized that the Infinity War will end in the destruction of the Avengers and the Earth, leading Dr. Strange to use the Timeline and return in time to Avenger 4 make movie dubbing. Others believe that the Timeline could be used to bring to The Mary future characters, such as the teen version of Ant-Man's daughter Cassie Lang, which was recently announced as part of Avengers 4 on the IMDB Sue. In the current Ant Man timeline, Cassie is still a little girl, so this casting message suggests either a massive leap in time or some time travel shenanigans.
Adding time travel to the MCU will only make the franchise even more confusing, but if it saves some of our favorite Avengers, it's all worth it.
