Life on Mars creators Ashley Pharoah and Matthew Graham have been commissioned by BBC Worldwide new drama czar Jane Tranter to write the script for an ABC drama pilot described as a "California cop show with a British twist." Should the project--executive produced by Julie Gardner--go to pilot, it would be produced by BBC Worldwide's Los Angeles production team and Pharoah and Gardner would remain heavily involved, unlike their limited creative involvement with the US version of Life on Mars.

CBS has cut back the episodic order this season for procedural drama Numb3rs from a full 22 episodes to just 16. Many, including Entertainment Weekly's Michael Ausiello, are viewing the decision as a sign that it might be the final season for Numb3rs and that Canadian co-pro Flashpoint might take over the Friday night timeslot. Elsewhere at the network, CBS increased the episodic orders for How I Met Your Mother, NCIS, NCIS: LA, CSI: Miami, and Two and a Half Men to 24 installments, while Criminal Minds, CSI: NY, The Big Bang Theory, The Good Wife, CSI, and The Mentalist, have all been bumped to 23 installments.

Entertainment Weekly's Lynette Rice is reporting that ABC, Mark Gordon, and Roland Emmerich are developing a series-based sequel to their upcoming disaster film 2012. “The plan is that it is 2013 and it’s about what happens after the disaster,” Emmerich told Entertainment Weekly. "It is about the resettling of Earth. That is very, very fascinating. (2012 writer/producer) Harald Kloser and I came up with the idea and we have the luxury of having a producer on the film who is a big TV producer, Mark Gordon. We said to Mark, 'Why don’t you do a TV show that picks up where the movie leaves off and call it 2013?' I think it will focus on a group of people who survived but not on the boats... maybe they were on a piece of land that was spared or one that became an island in the process of the crust moving. There are so many possibilities of what they could do and I’d be excited to watch it." (Entertainment Weekly's Hollywood Insider)
