I.S.S.: Who Stars In the Science Fiction Thriller

Director Gabriela Cowperthwaite’s ISS cast is packed with eclectic talents. Although not A-list actors, the six-person cast includes several notable faces in film and television. ISS was one of 2023 best science fiction thrillers set in space onboard the International Space Station (ISS). The ISS is the world’s largest space station, built by the collaborative efforts of NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada).

The movie’s plot centers around six astronauts – three Americans and three Russians. Although they enjoy each other’s company at first, when a nuclear war breaks out on Earth, their respective governments give them orders to commandeer the ISS by any means necessary. The movie follows the crew’s strategies to survive and overpower one another to ensure their government takes control of the space station. To help breathe life into Nick Shafir’s screenplay, here is the ISS cast and the characters they play.
