EXCLUSIVE: Fox is wrapping up a deal for Kieran Fitzgerald to write the script for a reality-based disaster movie loosely inspired by the BBC faux-documentary The Day Britain Stopped. It will be developed as a potential directing vehicle for Ridley Scott.

Film Rites’ Steve Zaillian & Garrett Basch are producing with Scott Free’s Scott, Michael Schaefer, and Elishia Holmes. Kira Goldberg is overseeing for the studio. Fitzgerald is currently adapting The Tiger for Plan B and Focus. He garnered attention for his script Bambi, based on the life of former CIA agent Luis Posada. He’s repped by CAA.

Film Rites & Scott Free both have first-look deals at Fox, where they also have Wool in development with J Blakeson attached to adapt and direct. Zaillian and Scott previously teamed on American Gangster.
