Teenage Groot made his first appearance in a post-credits scene in this summer’s Guardians of the Galaxy Vol. 2.
According to an interview with Yahoo, noted motion capture performer Terry Notary — best known as Rocket in the recent Planet of the Apes trilogy — will be portraying Teenage Groot in Avengers: Infinity War and, presumably, Avengers 4 as well.
With production on the untitled fourth Avengers movie going full steam ahead, its finally been confirmed who plays a key character in the two-part Marvel Saga.
The character’s great, and the films are going to be great.
