It’s been a little over a year since Rebecca Ferguson’s Juliette Nichols went outside to discover a new world beyond her Silo. As the Apple TV+ original has freshly returned to the 2024 TV schedule with its latest premiere episode “The Engineer,” we’re squarely focused on the Mission: Impossible star’s exploits outside of her former home.

As "Silo" Season 2 begins rolling out this week on Apple TV+, star and producer Rebecca Ferguson is eager to see the entire sci-fi story from the source material told onscreen. For that, she says they'll need about four seasons.

Steve Zahn is set to play an undisclosed role in Season 2 of Silo. Although not much has been revealed about his character, it looks like he’s bound to change the way the Deep Down works as he crosses paths with Juliette. Zahn is best known for his performances as Cobi in Mad Dogs and most notably Mark Mossbacher in Season 1 of The White Lotus.
