Captain Marvel movie: Avengers Infinity War writers open up on Carol Danvers' MCU debut

Stephen McFeely and Christopher Markus penned both Avengers: Infinity War and its as-yet-untitled follow-up.

The next Avengers film will be released after the 1990s-set Captain Marvel solo film, although it was written and filmed first.

This meant that the teams behind both Marvel films had to work together to ensure the Captain Marvel film set the character up correctly for what had already been planned in Avengers 4.

Speaking to Collider, McFeely said: “We were in the position we were in with Spider-Man and [Black] Panther where Brie [Larson, playing Captain Marvel] was going to have to shoot her scenes, I think it’s OK to say, before she shot Captain Marvel.”

He added: “We can’t really talk about what we decided but it was clearly a conversation we had to have with Ryan (Fleck) and Anna (Bodem, directors).

“So you are bringing directors on and we’re trying to set up something that will work for our movie and not screw up their movie.”

Captain Marvel is alluded to in the final post-credits sting of Avengers: Infinity War, when Nick Fury (Samuel L Jackson) is seen appearing to contact Carol Danvers.

“We thought, ‘do you want to give any hope?’” McFeely said. “It’s a tragedy and tragedies end in a grim and sad end.”

Markus added: “When you end it like that, there aren’t too many other places you can go [for a tag scene].

“Marvel tags often point to the next movie coming. The next movie is Ant-Man and the Wasp, which is light-hearted – you don’t wanna go, ‘but meanwhile! Paul Rudd is still adorable!’”

“We wanted to give a bit of hope to people,” McFeely reasoned. “And that was the best chance we had.”

Also on board for the Captain Marvel origin story are Samuel L Jackson as Fury, plus the likes of Jude Law and Annette Bening.

Bening remained tight-lipped when quizzed on her mysterious role in a recent TV interview.
