Since "Avengers: Infinity War" will soon begin production, it is expected to be the largest movie event in the entire Marvel Cinematic Universe as a lot of the characters in the MCU are confirmed to participate. Aside from the main Avengers squad consisting of Iron Man, Thor, Captain America, Hulk, Black Widow, Hawkeye, Scarlet Witch and Vision, here's a list of the characters that are going to appear in "Avengers: Infinity War."
Doctor Strange
The "Doctor Strange" standalone film basically set up the MCU for Phase 3. It introduced the supernatural aspect of the MCU and opened doors to more expansive worlds and possibilities. It is only apt to have Benedict Cumberbatch reprise his role as the Sorcerer Supreme in "Avengers: Infinity War."
Although he did not specifically mention "Infinity War," Cumberbatch mentioned that one of Marvel's biggest "logistical challenge" is to line up his schedule with Robert Downey Jr., Chris Hemsworth, Paul Bettany and Elizabeth Olsen - all of whom are known members of the Avengers.
"To get us all together will be quite something. That's why this character is being introduced, to open up the next chapter," Cumberbatch told Empire (via Express).
Spider-Man
After Tom Holland makes his solo debut in "Spider-Man: Homecoming," he will join the rest of the superhero gang in "Avengers: Infinity War." In an interview with L'Uomo Vogue, the young actor revealed that Robert Downey Jr. and Chris Evans convinced Marvel that he's the right man for the job.
"[The] producers wanted to be sure that I was the right person before entrusting three films over the next four years, including 'Avengers: Infinity War,'" the article read, as translated by Comicbook.com.
Gamora and Star-Lord
Chris Pratt was one of the actors earlier confirmed for "Avengers: Infinity War." His "Guardians of the Galaxy" co-star Zoe Saldana is also joining the supersized film as Gamora. The rest of the Guardians are also presumed to join.
Betty Ross
This hasn't been confirmed yet, but a report suggests that Liv Tyler is heading to Scotland to join the filming for "Avengers: Infinity War." It can be recalled that Tyler previously portrayed Betty Ross, the love interest of Edward Norton's version of The Hulk. She's hasn't reprised the role since then, but it would be a surprise to have her on "Infinity War."
Thanos
Josh Brolin is returning as Thanos in "Avengers: Infinity War. In an interview, he teases that he was "completely blown away" by the movie's story.
Nebula
Karen Gillan played the villain Nebula in "Guardians of the Galaxy." If the comics are to be followed, Nebula is going to have a significant role. She manages to get her hands on the Infinity Gauntlet and extract vengeance on Thanos. The Infinity Gauntlet also emphasizes Nebula's disturbed state of mind, making her even more cruel and unreasonable.
