Avengers 4: 11 Insane Trailer Rumours You Need To See

6. Thor & Valkyrie Hunt Down Captain Marvel

One of the more intriguing rumours so far is that the trailer will see Thor and Valkyrie (Tessa Thompson) somehow ending up aboard a Kree ship in search of Captain Marvel (Brie Larson).

If the description is correct, Thor will tell her, "If the stories are true, you’re our universe’s last hope. If such a thing even exists anymore."

This is especially telling as it not only suggests how Carol Danvers will be integrated into the quest to stop Thanos, but also that Valkyrie will in fact appear in the film despite Thompson not yet having an officially credited role.

Considering that both Thompson and Hemsworth flew to Atlanta for Avengers 4 re-shoots recently, it seems probable that Valkyrie will indeed appear in the movie. Joe Russo has already confirmed that she did in fact survive Thanos' assault at the beginning of Infinity War, so leaving her on the bench for Avengers 4 would be pretty bizarre.

More to the point, having Thor, Valkyrie and Captain Marvel hanging out should present some strong dramatic and comedic possibilities, just as when Thor met up with the Guardians in Infinity War.
