Talk about a spook before bedtime, Steven Spielberg is working on a new horror show that you will only be able to watch at nighttime. 

The multi-award winning director is writing the horror series for Quibi, a brand new mobile screening service, that viewers will only be able to watch once the sun goes down. 

According to Variety, Spielberg told Quibi creator Jeffrey Katzenberg that he had a "super scary story" he wanted to do.

Katzenberg said: "He's writing it himself. He hasn't [written anything in a while] so getting him to write something is fantastic."

Katzenberg added that Spielberg has already "written five or six episodes of a 10 or 12-chapter story." The program is being developed under the title Spielberg’s After Dark.

Spielberg really only want people to view the show in the dark, so Quibi engineers have developed a clock that will appear on viewers phones, tracking the sun set. The clock also tracks when the sun comes back up, and the show will then be unavailable until it is dark again. 

Quibi is set for an April 2020 launch.
