Josh Brolin, who plays Thanos in the MCU, has confirmed that the actor will share at least one scene with Captain Marvel star Brie Larson. As Larson’s character isn’t expected to appear in Avengers: Infinity War, there’s a strong chance the scene will take place in Avengers 4.
Though there has been much confusion over whether or not Carol Danvers will appear in Avengers: Infinity War prior to the release of Captain Marvel in 2019, it’s been repeatedly stated that Captain Marvel will not be in Infinity War, which means fans will have to wait for Avengers 4 to see Captain Marvel join forces with Earth’s Mightiest Heroes.
Though the scene is most likely in Avengers 4, some fans believe that Captain Marvel could still appear in Infinity War as a last-minute cameo in a post-credits scene that could set up her arrival.
As Thanos is expected to be the main villain in Avengers 4, it’s not surprising that he’ll eventually meet Captain Marvel.
