A cast list for 2018's Avengers: Infinity War movie has been floated around by a prominent casting agent, listing Brie Larson's Captain Marvel as well as the full Guardians of the Galaxy team as appearing. MovieCastingCall lists them among the returning stars of Avengers: Age of Ultron, as well as Karen Gillan's Nebula, Chadwick Boseman's Black Panther, Benedict Cumberbatch's Doctor Strange, Paul Rudd's Ant-Man, and Benedict Wong's Wong.
Larson's Captain Marvel solo film is scheduled for release March 8, 2019, before the untitled fourth Avengers film. Avengers: Age of Ultron writer/director Joss Whedon has previously said that Captain Marvel was pencilled in to debut in the final moments of his 2015 film, but was nixed by Marvel Studios.
Avengers: Infinity War is scheduled to begin filming this January in the Atlanta-area's Pinewood Studios for a planned May 4, 2018 theatrical release.
