Casting is currently underway for a female lead to headline an ensemble cast, with Jason Momoa (Aquaman, “Game of Thrones”) in talks for a cameo.
(The leader of the villains in the original is an excellently demented John Lithgow.)
Momoa appeared in Amirpour’s previous film, The Bad Batch.
The only cameo that really makes sense here for him (assuming the remake is like the original) would be playing the person who (uh, spoiler alert) dies in a climbing accident in the film’s opening scene.
