Cowards looks interesting.
Also "Daydream Believers" the new pilot from Mitchell & Webb is booked up. This is what it's about:
Daydream Believers
A pilot for a new show written by and starring David Mitchell and Robert Webb (Peep Show).
Ray (Mitchell) writes best-selling science fiction stories, and he spends at least a week writing each novel or the quality suffers.
All the pointless interruptions from his lodger Colin (Webb) would put Ray off, if he didn't find ingenious ways of incorporating their conversations into the thrilling space adventures of hard-working Baron Amstrad and his constantly interrupting robot companion Info (also played by Mitchell and Webb)
Sounds funny.
