Although we are currently in a kind of intermediate phase in the MCU, new exciting projects and ideas for the future of the MCU are presented almost weekly. One of the most anticipated films is James Gunn's Guardians of the Galaxy 3, and one of the central questions for fans is whether or not Thor will actually appear in the third Guardians part, considering the events in Avenger's endgame. Recently, Star-Lord actor Chris Pratt was asked by a journalist why Thor won't appear in the third Guardians part. Pratt replied that the film hasn't been shot yet and therefore a clear yes or no to the question is out of place.
So fans shouldn't give up hope for Thor's appearance in the Guardians yet, as there's still some time until the release.
