Vulture broke the news today that 'Awake,' NBC's promising mid-season drama about a cop who travels between two different realities, is halting production for four weeks while executive producers Howard Gordon and Kyle Killen figure out how to move forward with the show.

"There's a certain trial and error process with any creative endeavor," Gordon said in an interview with AOL TV on Wednesday. "It's really a math and business decision married to a creative decision. We could have kept going, but we felt we could learn from our mistakes."

Those mistakes, Gordon said, are not major; he said that the studio and network are "happy" with what they've seen so far. But 'Awake,' which stars Jason Isaacs as a cop whose son is dead in one reality and who finds himself a widower in the other, debuts at mid-season and thus has what Gordon called "the luxury of time." The temporary production halt means that Killen and Gordon can spend those weeks fine-tuning their approach well before the show debuts (probably in January, Gordon said).
