Looking forward to Spider-Man and Captain Marvel's debut in the Marvel Cinematic Universe? Well, you almost got it early, in Avengers: Age of Ultron.
In an interview on Empire Podcast, director Joss Whedon revealed that he had plans to include both in the film. Spoilers ahead!
Whedon's plans were to include both as part of the line-up introduced at the end of the film where Captain America and Black Widow are training the new recruits as Avengers.
"I wanted all of those people. I said, 'It would be great if we could just add a few more. If we could have a Captain Marvel there, that you've made a deal for.' And they talked about it,"says Whedon. "And I was like, ‘And Spider-Man, we could do that too, because Sony had approached us during the first movie about a little integration.' So, I would have put both of them in, but neither of the deals were made."
Filming of Avengers: Age of Ultron was already underway when the Captain Marvel movie was announced, and Marvel's deal with Sony for Spider-Man didn't come together until after the bulk of filming had completed -- but by then, it was too late said Whedon.
"And then they're like, ‘We’re making a Captain Marvel movie and we’ve got Spider-Man as a property,’ and I’m like, ‘I’ve already locked my film you f***ers! Thanks for nothing.'”
