One of Marvel’s most powerful superheroes is finally joining the Marvel Cinematic Universe. Will Poulter (“Midsommar”) has landed the role of Adam Warlock in “Guardians of the Galaxy Vol. 3,” which writer-director James Gunn is set to start shooting later this year. “Welcome to the Guardians family, Will Poulter,” Gunn posted to Twitter on Monday. “He’s an amazing actor and wonderful guy. See you in a couple weeks.” The British-born Poulter made his feature debuts in 2007’s “Son of Rambow” and 2010’s “The Chronicles of Narnia: The Voyage of the Dawn Treader.” Most audiences, however, likely first remember him as the awkward teenage kid in 2013’s “We’re the Millers” who is bitten on his testicles by a tarantula. Poulter has also played standout roles in “The Maze Runner” franchise and 2015’s “The Revenant,” and he can currently be seen in the limited series “Dopesick” on Hulu. Gunn teased the introduction of Adam Warlock in one of the mid-credits teasers in 2017’s “Guardians of the Galaxy Vol. 2,” after Ayesha (Elizabeth Debicki), leader of the Sovereign people, creates a being she names “Adam,” with the purpose of destroying the Guardians of the Galaxy. “Guardians of the Galaxy Vol. 3” is scheduled to debut on May 5, 2023.
