John Boyega and Letitia Wright have been tapped to star in the upcoming film adaptation of Katie Khan’s novel Hold Back the Stars.

The British actors are both on a roll and in demand right now starring in the major franchises Star Wars and Black Panther, respectively.

Mike Cahill is directing, and Christy Hall is the writer.

Here’s the description of Khan’s novel, released last year: Trapped in the vast void of space, Carys and Max have only 90 minutes of oxygen left to live. None of this was supposed to happen. After a freak accident, Carys and Max are left adrift in space with nothing to hold onto but each other. As they fall, they can’t help but look back at the world they left behind. A world whose rules they couldn’t submit to, a place where they never really belonged; a home they’re determined to get back to because they’ve come too far to lose each other now. While their air ticks dangerously low, one is offered the chance of salvation—but who will take it?

Both are returning for their respective Star Wars and Black Panther films, with Wright also appearing in Avengers 4 in 2019.
