Since the release of Avengers: Infinity War last year, fans have been patiently waiting to watch the 4th Avengers movie, which picks up right after Infinity War.

The Marvel cinematic community has grown exponentially over the years and does not only compromise of comic book nerds. Spoilers have been floating all over the internet and we’ve all been trying to duck those for months now. But this producer may have revealed a little too much than he wanted to.

It goes without saying, but a major spoiler awaits you. So read further at your own discretion.

Earlier this week, we found out that a character from the Captain America films, Crossbones, will also have something to do in Avengers 4. But now, we’ve learnt that The Ancient One from Doctor Strange will also be appearing in the film.

When asked about the crazy shooting schedule of the fourth Avengers film, at the Austin Film Festival, producer Michael Grillo, while answering, revealed that they spent a day shooting with Tilda Swinton.

“When we got Tilda Swinton, she was just a 1-day availability,” he said.

Swinton played The Ancient One, an important character in the 2016 standalone Doctor Strange film, who was killed off.

Since the reveal, fans have been making up new theories, and exploring previous ones that mentioned The Ancient One being heavily involved in the story. Even though, we’ve learnt from Michael that she shot for just a day, that doesn’t mean the role she’ll play won’t be important.

Nobody can say anything for sure, and all we can do is discuss theories and speculate, till next year when the Avengers return. Or will they?
