Maggie is played by Maggie Grace, the 43-year-old American actress best known as Shannon Rutherford in Lost and Kim Mills in the Taken franchise. In Below, Grace's character serves as the crew's medic and the primary voice of reason as the snot-berg organism escalates, a role The Guardian's October 8, 2026 review described as the series' most grounded performance amid the creature chaos.

How many episodes does Below Season 1 have and when did it premiere?

Below Season 1 consists of eight episodes, all released simultaneously on Netflix on October 8, 2026. The limited-series format means there is no weekly rollout, and Netflix has not yet confirmed a Season 2, though the show's early streaming performance and the volume of "below netflix cast season 1" searches suggest renewal talks are active.

Where have you seen the Below Netflix actors before?

Most of the Below Netflix actors are recognizable from major franchises: Josh Hartnett from Oppenheimer and Trap, Maggie Grace from Lost and Taken, and Ryan Kwanten from seven seasons of True Blood. Mila Harris appeared in No Exit and The Last Thing He Told Me, while Enuka Okuma is a veteran of Rookie Blue and the Canadian sci-fi series Impulse. According to Rotten Tomatoes (October 2026), the cast's familiarity is one of the few elements critics agreed works in the show's favor.

Is Below connected to Below Deck, Below Zero, or Eight Below?

No. Below on Netflix is an original scripted monster thriller and has no connection to Bravo's Below Deck reality franchise, the Spanish survival film Below Zero, or the 2006 Paul Walker dog-sled movie Eight Below. The shared word "below" drives most of the confused search traffic, but the 2026 Netflix series is a standalone Josh Hartnett project with a completely separate cast and production team.

What do critics say about the Below Netflix cast and series?

Critics have been mixed on the series but largely positive on the cast. The Guardian's October 8, 2026 review praised the show's creature design and Hartnett's committed performance, while IndieWire criticized the thin plotting but acknowledged the production values. Rotten Tomatoes' first-reviews roundup framed Below as "a monster horror worth watching," citing the cast chemistry between Hartnett and Grace as a key strength.

Will there be a Below Season 2 with the same cast?

Netflix has not officially renewed Below for Season 2 as of October 9, 2026, so no cast return has been confirmed. Given the limited-series structure and the show's strong debut search volume, industry analysts expect a renewal decision within 60 to 90 days, with Hartnett and Grace contractually positioned for a potential return.
