Vanessa Kirby and Lewis Pullman Blast Off With New Sci-Fi Epic: Title and First Plot Details Revealed

So, here’s a fun development that isn’t just another day in the Marvel factory: Lewis Pullman and Vanessa Kirby—two folks you’ll start seeing everywhere thanks to Marvel—are about to team up in a totally different kind of sci-fi film. No capes, no infinity stones, just space, tension, and (allegedly) some high-stakes drama. It’s called 'The Spaceship,' and there are a few genuinely interesting things going on in this one.

Wait, Pullman and Kirby Again?

If you’re getting MCU déjà vu, you’re not wrong. Both Pullman and Kirby are about to earn their Marvel badges—Pullman’s set to blast onto the scene as Sentry (and let’s be clear, also the Void and Robert 'Bob' Reynolds—that’s three roles, same film) in the upcoming Thunderbolts*, while Kirby will make her superhero entrance as Sue Storm, AKA the Invisible Woman, in The Fantastic Four: First Steps. Both debut in 2025, and Marvel obviously wants to cash every possible check those castings can write.

And yes, both are sticking around the Marvel universe: they’re locked in for Avengers: Doomsday—which is already shaping up to be the most overcrowded Marvel movie in recent memory. We’re talking over 25 familiar faces, with literally everyone (Fantastic Four, OG Avengers, New Avengers, Wakandans, the original X-Men) piling in to duke it out against... Robert Downey Jr. as Doctor Doom. No, you’re not misreading that.

So What’s 'The Spaceship' About?

This isn’t some generic space romp or alien invasion flick. Here’s the setup: Vanessa Kirby plays an astronaut facing a genuinely ugly decision after her co-pilot (Pullman) gets involved in a serious incident days before lift-off. Whatever happens, it torpedoes the mission vibe, and suddenly it’s a frantic countdown to fix—well, something—before time runs out. The movie’s pitched as giving a “timely and provocative new perspective” on what it means to go beyond Earth. (Your move, “realistic” space movies.)

Directing and writing is Kitty Green—if you saw The Assistant or The Royal Hotel, you know she doesn’t do standard studio fare. Producers include James Schamus, Scott Macaulay, Joe Pirro, Rita Walsh, and Kath Shelper. Vanessa Kirby and Juliet Kirby are exec producing, because apparently Hollywood’s smallest club is “family members named Kirby making movies together.”

Behind the Scenes & The Business End

• Director/Writer: Kitty Green
• Stars: Vanessa Kirby, Lewis Pullman
• Producers: Green’s usual suspects (James Schamus, Scott Macaulay, Joe Pirro, Rita Walsh, Kath Shelper)
• Exec Producers: Vanessa & Juliet Kirby
• Sales: HanWay Films is shopping it around Cannes for international buyers; UTA Independent Film Group and CAA Media Finance are handling North American deals

Release Plans & Marvel Crossovers

There’s no set release date for The Spaceship yet—Cannes will probably give a better clue how quickly it’ll land in theaters. Meanwhile, both Pullman and Kirby are pretty much Marvel mainstays now: they’ll be back for Avengers: Doomsday, directed by the Russo brothers (yep, those guys) and produced by Kevin Feige. That one drops December 18, 2026. Expect chaos.

'The Spaceship follows an astronaut (Kirby) who is forced to make an impossible decision after an incident with her co-pilot (Pullman) leaves an indelible stain on the mission in the days leading up to lift off, setting off a tense race against the clock.'

Long story short: yes, all roads lead to Marvel, but at least Pullman and Kirby are sneaking in some ambitious non-franchise work on the side. That’s probably healthy for everyone, honestly.
