EXCLUSIVE: As NBC‘s sophomore comedy Up All Night transitions from a single- to multi-camera format, it will do so without the series creator/executive producer Emily Spivey, who has departed the show. There has been a lot of behind-the-scenes turnover on the series starring Christina Applegate, Will Arnett and Maya Rudolph since May when original showruuner Jon Pollack left. He was replaced by Tucker Cawley who, in turn, was replaced by Linda Wallem when NBC decided to revamp Up All Night as a multi-camera comedy after 11 softly rated episodes of Season 2. Along with the format switch, Up All Night will undergo creative changes, including in the balance between family and workplace comedy, that are still being worked out. In its original incarnation, Up All Night was a family comedy about new parents played by Applegate and Arnett, which was inspired by Spivey’s real-life experiences of going back to work soon after giving birth. The workplace element was expanded when Rudolph was cast as Applegate’s boss.
