EXCLUSIVE: Zachary Levi is back on pilot duty and back on the half-hour comedy beat. The Chuck star has been tapped as the male lead of Fox’s single-camera comedy pilot Let It Go, lifting the cast-contingency on the project. Let It Go, from Sony Pictures TV, is an ensemble comedy about a married couple, the husband played by Levi, his best friend and her sister as they try to navigate, negotiate and sometimes manipulate society’s unspoken rules. DJ Nash wrote the script and is executive producing with Peter Tolan and Michael Wimer. This marks Levi’s return to half-hour comedy series following his breakout role on ABC’s Less Then Perfect. From it, he segued to spy dramedy Chuck, which just finished its five-season run on NBC. Levi was one of the most sought-after actors this pilot season, fielding at least half a dozen offers.
