The series was one of the most-hyped at last year's New York Upfronts and its pilot earned rave reviews. However, the show has struggled in the ratings for NBC since it began airing earlier this year and a second season has yet to be confirmed.

> Jason Isaacs: 'Awake is a high-concept risk'
Awake centres on Isaacs's character Michael Britten, a cop who lives in two worlds - one in which his wife died in a car crash and another in which his son was killed.
Speaking about the project earlier this year, the Harry Potter actor said: "There's a risk Awake is too high-concept for US networks. The US shows I love - Mad Men, Sopranos - would never work on network TV. This has to work on network TV, like House or CSI.
"Lots of shows get canned mid-series because they didn't sell to middle America. If it flops, I'll live with it. I don't want to be in crap."
It is exec produced by Kyle Killen (Lone Star), Jeffrey Reiner (Friday Night Lights) and Howard Gordon (Homeland, 24).
"Sky Atlantic is committed to bringing the best drama exclusively to our customers. Awake with its stellar cast and intriguing plot lines, together with Game of Thrones and Smash will ensure Sky Atlantic has the perfect drama schedule this spring," said Sky's director of acquisitions Sarah Wright.
Awake will launch on Sky Atlantic in late Spring.
