Adam Sandler as Jakub Procházka

I think by now most of the world knows who Adam Sandler is, especially if you're a long-time Netflix subscriber as the actor and comedian has made several movies for the streaming service at this point, including Leo, You Are So Not Invited to My Bat Mitzvah, Murder Mystery, Hustle, Hubie Halloween, and more.

Outside of Netflix, he's starred in a mixture of comedies and even some dramatic films like Uncut Gems. After breaking out on Saturday Night Live, Sandler has created a legendary career for himself, netting many accolades like five Emmy Award nominations and a Screen Actors Guild Award.

In his latest movie Spaceman, Sandler takes on another dramatic role by playing the astronaut Jakub Procházka. While on a lonely and isolating trip to the edge of the solar system, Jakub meets a creature from the beginning of time who helps him understand why his marriage is falling apart and where he's fallen short as a husband.

Carey Mulligan as Lenka

Carey Mulligan is another big-name actress and she's currently in the headlines for her acclaimed performance in the Academy Award-nominated movie Maestro, which has earned her a Best Actress nod at the upcoming Oscars, marking her third overall nomination after Promising Young Woman and An Education. Next, the English actress is slated to star in the comedy film One for the Money and the stop-motion fantasy Wildwood.

Mulligan plays Jakub's pregnant wife Lenka in Spaceman. Most of our time spent with her is through his various flashbacks while he talks to Hanuš on the space shuttle, but she also has her own journey in the movie as she grapples with her crumbling marriage and life with her husband gone so often.
