Doctor Strange is perhaps one of the most important players when it comes to the Avengers’ battle against Thanos. At a point where all hope seems to be lost, Doctor Strange looks into all potential futures (which amounted to more than 14 million) and discovered one possibility in which our heroes win. Strange’s discovery eventually leads to Iron Man’s sacrifice and the defeat of Thanos as we see in Avengers: Endgame.
But how exactly did Strange travel through time? In a recent interview with Wired, Endgame directors Joe and Anthony Russo were asked that exact question. As one might expect, the Russo brothers compared the events of Infinity War with what happened during the climactic scene of Doctor Strange which sees the Sorcerer Supreme go up against Dormammu.
Anthony Russo: Strange has to exert an immense amount of energy to go into this state and the amount of time he’s in this state, as we know from his history in his own standalone film Doctor Strange, he can be in the state for who knows how long. It could have taken Strange an immensely large time to review all these scenarios.
Joe Russo: He has to physically review all of these scenarios and die in them and right before he dies, he has to reset it as we saw at the end of Doctor Strange, and do it again, taking copious notes each time he does it.
Avengers: Endgame is now available to purchase on Blu-ray and digital form.
