EXCLUSIVE: NBC has pulled the plug on midseason comedy series Next Caller. The network in May had given the Dane Cook-starring project a six-episode order. After filming four of them, I hear network brass had decided that creatively the series was not going in the direction they had hoped for. Production on the series, produced by Lionsgate TV and Universal TV, has stopped, and the produced episodes won’t air. Created and executive produced by Stephen Falk, Next Caller stars Cook as a foul-mouthed satellite radio DJ forced to share the mic with a chipper NPR feminist (Collette Wolfe). Jeffrey Tambor, Joy Osmanski and Wolé Parks co-star. NBC recently gave two of its freshman comedy series, Go On and The New Normal, full-season pickups, while fellow freshmen Guys With Kids and especially Animal Practice, have been struggling. The network has two other comedy series on tap for midseason, 1600 Penn and Save Me.
