As well as developing a block of original sci-fi programming for TNT, the ever-busy Ridley Scott is currently working on a vampire show for FOX – and said show has now moved to bring in its first cast members.

To be executive produced by Scott and Matt Reeves, post-apocalyptic vampire pilot The Passage has signed up Mark-Paul Gosselaar as its lead. Gosselaar famously burst to stardom as Zack Morris in Saved by the Bell before going on to feature in the likes of NYPD Blue, Franklin & Bash, Pitch and the criminally underrated Dead Man on Campus. As well as Gosselaar, Variety is reporting that American Horror Story’s Saniya Sidney, Tusk’s Genesis Rodriguez, and Brianne Howey and Jennifer Ferrin are also to star in The Passage.

The early word on The Passage reads:

The Passage is based on Justin Cronin’s best-selling trilogy of the same name, and is described as an epic, character-driven thriller that morphs into a post-apocalyptic odyssey, which spans over a century and is told across two timelines. The story focuses on a 10-year-girl named Amy Bellafonte (Sidney) who must save the human race.

Mark-Paul Gosselaar will be playing an FBI agent targeted for a sinister government experiment, who ends up on the run with young Amy as they have to constantly stay one step ahead of their would-be captors.

The pilot for The Passage is set to shoot later this month over in Atlanta, and the hope is to get a full season ordered and lined up for the 2017-2018 TV season.
