Avengers: Infinity War screenwriters Christopher Markus and Stephen McFeely previously revealed that the powerful Marvel cosmic being known as the Living Tribunal appeared in an early draft of the film's script.
Markus and McFeely explained that the Living Tribunal was originally set to appear during the fight between Thanos, Doctor Strange, Iron Man, Spider-Man and the Guardians of the Galaxy on the planet Titan. During their panel at Comic-Con International in San Diego, Markus and McFeely revealed new details regarding what this scrapped sequence would have entailed.
"We didn't lose it. We took it out!" Markus explained when asked about the cut scene by the panel's moderator. "It was partly inspired by Kevin Feige... he came into the conference room in Atlanta, where we were trapped for years, and he had brought a bunch of comics panels with him... we were pretty far down the road... and he wanted to make sure we didn't lost the psychedelic nature of the [Jim] Starlin universe... and so we stuck the Living Tribunal in the movie. So, as Thanos and Doctor Strange came to blows, Doctor Strange blew Thanos' mind and sent him through the mindscape."
"Not unlike the Ancient One did to Doctor Strange in Doctor Strange," McFeely added. He then explained that this sequence would have shown Thanos being faced by all the atrocities he committed against the universe. "In the end, he would have been dumped in front of the Living Tribunal, who judged him guilty."
Originally created by Stan Lee, Marie Severin and Herb Trimpe, the Living Tribunal serves as the judge, jury and executioner in universe-shaking affairs. In the Marvel comic books, the Tribunal permitted Thanos to wield the Infinity Gauntlet. Once all was said and done, however, the powerful entity declared that no one being could ever combine the Infinity Gems again.
During the panel, Markus explained that Avengers: Endgame was "99 percent done" by the time Infinity War was released. With two major projects being worked on at the same time, certain things were bound to be left on the cutting room floor.
"You get handed these two movies and your first reaction is panic, because that's a lot of work, and if it's bad, you'll be very embarrassed... and then you have to wait around because you're going to be embarrassed next year," he said. "[Feige[ just said stick the landing... if that means cutting the Guardians out of the movie, if that means shrinking it to make it more manageable... do it."
