Marvel Studios CEO Kevin Feige reveals that Captain Marvel almost appeared in "Avengers: Age of Ultron."

Feige revealed that "Ultron's" director Joss Whedon wanted Captain Marvel to appear in the very last scene of the film, but thought it was an unfitting way to introduce the character.

"It was in the script at one point, it might have been one draft. Was it... It might have just been Captain Marvel," he said in a statement published by Screen Rant. "And we shot a plate and thought we may add her in there but the truth is it just didn't seem appropriate to have this new person in a new costume come out of nowhere at the end of this story."

Note that Marvel had yet to confirm the "Captain Marvel" movie was happening at the time "Avengers: Age of Ultron" released in theaters.

"It would have been a disservice to, what by the time the movie was coming out, a character people already knew was coming anyway. And also what does Captain America say? 'They're not the 27 Yankees.'"

Before any cameo to take place, Marvel must first cast an actress to play the heroine. Despite the rumors that "Mission: Impossible" star Rebecca Ferguson is circling the project, Feige confirms that the studio has yet to cast Carol Danvers.

"There won't be any announcements about that this year," said Feige in a separate interview published by MTV News. "I think right now we're scripting the film, figuring out who we want Carol Danvers to be, and really what the structure of the movie will be and what her part will be in some of our other Phase 3 films. And it would be next year that we start to really think about casting."

"Captain Marvel" releases in theaters on March 8, 2019.
