We were devastated after we saw the end of Avengers: Infinity War, where, spoiler alert, we saw Thanos snap his fingers and clear out most of the universe. Recently, one of the film's stars shared just how he found out his character's fate in the Marvel universe.

During a recent appearance at Wizard World's comic con in Philadelphia, Sebastian Stan, who plays Bucky Barnes in the films, shared how he found out about Bucky's fate at the end of the move, saying:

“I remember the day on set and James Young, who is one of my talented, glorious stuntmen … on this film, came up to me and actually told me what was happening,” Stan said. 

According to Stan, Young came up to him to explain the scene that revealed Bucky's fate, simply sharing that all he'd have to do is fall onto a mat, consequently disappearing from existence. Of course, if he had any questions, Young told him that directors Anthony and Joe Russo would further explain it. 

With a simple, “oh, okay,” to Young, Stan continued on to say: 

“And I was like, 'maybe this is it.' And I remember Anthony was talking to everybody, and I was like, 'Anthony, do- OK, I'll wait. Am I- uh, is this it?'

“And he was like 'No, well, you know, maybe. But not really. Well, I don't know.' So, that's the way that day went.”

Watch Stan's appearance below:

While Bucky's fate in the franchise is uncertain, Stan has previously shared his own thoughts on what Marvel could do with his character. In a recent interview with Variety, Stan hinted that he wouldn't mind seeing Bucky get his own movie, especially if he could explore the character's backstory more. 

“Of course,” the actor said. “I mean, the thing about these movies is that we’ve had a lot of them, but at the same time, there’s always pieces you feel like you can still explore and go back. Every time you play the character you learn something new and you want to go back and do it, so of course.”

Stan even shared that the solo film could show more of Bucky’s past, saying:  “To get into some of the past, for example, that we haven’t seen then I’d be down 100 percent.”

We’d be down 100 percent to see that, too. 

Of course, Bucky isn't the only hero we're worried about.

In a previous interview with ABC's Good Morning America, Chris Evans shared that things are looking uncertain for three original cast members, as their contracts are ending after Avengers 4, saying: 

“Well, the contract is done. A lot of our contracts are through,” Evans said, pointing out that not only his contract is ending, but the contracts of Iron Man (Robert Downey Jr.) and Thor (Chris Hemsworth.) “Myself, Downey, Hemsworth, we all kind of started roughly at the same time, and I think we all, through Avengers 4, kind of wrap it up. So at this point, I don't know what's next, but yeah, by 2019, that's it.”

Of course, this isn't the news we wanted to see or hear. (Say it ain't so Chris!)

With the news that their contracts are up after the fourth instalment of the franchise, we can't help but feel a little worried about the superheroes we've grown to love.
