But as the movie’s sequel – currently only referred to as Avengers 4 – is filmed, we do have early signs of who won’t be bumped off.
Gwyneth Paltrow, playing Pepper Potts, let slip in an interview that she’s been with Robert Downey Jr and Don Cheadle on set – meaning they’re both highly likely to at least make it through next summer’s big blockbuster.
She told The Hollywood Reporter: “I went to Atlanta to do Avengers 4, so I’m in and out for that, and it’s weird to go back and forth.
“We’re growing fast, and balls are dropping all the time. But honestly, I was on set and thought, ‘You sit here for two hours sipping tea, Robert Downey Jr. and Don Cheadle are making me laugh hysterically – why the hell did I give this up?’”
Of course, that doesn’t mean that their lives are assured for that film as well – but at least they can (seemingly, at least) be ruled out of meeting a Thanos-initiated demise in Infinity War.
Paltrow’s interview was about her Goop brand, and she also spoke out about her experience in acting has helped her with business.
“When you are an actress on a set, an unspoken component of your role is an energetic one to maintain balance and communication, which is a very feminine impulse,” she said.
“For me, when I’m on set, I try to make sure the energy is clean and people can communicate in a safe space, and that’s what I bring to my leadership here at Goop, too.”
She also insisted that she has “no desire” to move into film directing.
Her return as Pepper Potts was first confirmed earlier in the summer.
Avengers: Infinity War is out in spring 2018.
