Titannus could be a possibility as the supporting male role, having gone through the Super-Skrull program. The alpha female could be Skrull princess Anelle, Mar-Vell’s lover (the original Captain Marvel, played by Jude Law in the film).
Marvel Studios President Kevin Feige felt that the Captain Marvel movie presented the best opportunity for the Marvel Cinematic Universe to dive into the Kree/Skrull war.
He explained: “Captain Marvel will be our 21st film in the cinematic universe, and we’ve never seen the Skrulls. How come? We thought it would be fun. There’s an entire section of our comics that deal with the Kree/Skrull war, and we haven’t tapped into that at all, and we thought that would be an amazing, huge part of the mythology to belong to Captain Marvel.”
Captain Marvel will be flying into theaters on March 8th, 2019.
