Twenty years ago, Stephen King adaptations fell into two groups: theatrical releases for film adaptations, and mini-series for television. The multi-night mini-series is a long dead format, so CBS has done the next best thing when adapting Stephen King's Under the Dome to television: develop it as a TV series.
The network, which does not often delve into genre programming (their last genre project was the short-lived werewolf procedural Moonlight in 2007) has ordered Under the Dome straight to series, giving it a 12-episode order with plans to air during the network's summer programming push. CBS will co-produce with Steven Spielberg's Amblin Television. Comic writer Brian K. Vaughan scripted the pilot, with Niels Arden Oplev (The Girl with the Dragon Tattoo) on to direct.
Under the Dome details a small town who suddenly find themselves housed beneath an invisible, impenetrable dome and find the situation within quickly turns post-apocalyptic.
