Meet the Cast of Netflix's Latest Reboot, Lost in Space

This Deadwood and House of Cards alum plays Robinson matriarch Maureen, a brilliant aerospace engineer who is the instigator behind taking her entire family into space for a chance at a new life. Part of this involves forgiving her husband for something (the show hasn't revealed that yet, but it sounds like an affair) and rekindling the love they once shared.

Stephens plays John Robinson, Maureen's husband and a combat veteran who commands the expedition. You may recognize Stephens from Black Sails, but a fun bit of trivia is that he's also Maggie Smith's son. Stephens is also an accomplished stage actor in both Britain and the US.

This young actress has previously appeared in TNT's sci-fi series Falling Skies and Lifetime's Unauthorized Saved by the Bell Story in which she played Lark Voorhies (Lisa Turtle). On Lost in Space, she plays the Robinsons' eldest daughter, Judy. In this reboot, Judy is Maureen's daughter from her first marriage, though she never knew her biological father and was adopted by John at a young age.

The classic middle child, Penny Robinson is sociable, funny, and constantly struggling to get her parents' attention. She is played by Sundwall, who up until now has only appeared in small roles on TV and in a handful of movies.

Jenkins got his start in entertainment performing acrobatics in the circus with his family's company, then later appeared in recurring roles on Sense8 and Chicago Fire. This 12-year-old plays youngest Robinson child, Will, who is eager to leave Earth because he has been picked on and bullied by kids his own age. Will is sensitive, empathetic, and shy, though the Robinsons' space adventure lets him find his courageous side.

This Hollywood veteran — Posey has been in dozens of TV shows and movies over the years, including Best in Show and A Mighty Wind — plays Dr. Smith, a mysterious character whom you'll never quite be able to figure out. Is she a hero? A villain? A saboteur? We can't wait to find out.

This Argentina native, best known for his regular role on General Hospital, plays Don West, a contractor and smuggler who doesn't approve of the colonization of other planets.
