Stewart described the movie as “a really dark, scary meditation on isolation” inEntertainment Weekly‘sfirst look.

“I haven’t made a movie of this scale maybe ever. It was not an easy movie to make — really long and just drippy and cold and f—ing hard,” Stewart admitted toEW. And it didn’t play to her strengths either, the star added: “I really don’t like being held down, I don’t like confined spaces, I’m not a strong swimmer.”

Yet the film had its lighter moments.

“There’s some comedy in the movie every once in a while; in the most dire situations you kind of laugh in a funeral,” Stewart said. “That’s kind of what it felt like to make the movie as well. Like we were all dying!”

Stewart stars in two more upcoming thrillers as well: Elizabeth Banks’remake ofCharlie’s Angels, out Nov. 15, andSeberg, the biopic of American-French actress Jean Seberg, which will receive its world premiere Aug. 30 at the Venice Film Festival.Banks recently told PEOPLEStewart is the “secret weapon” ofCharlie’s Angels.
