EXCLUSIVE: Will & Grace creators David Kohan and Max Mutchnick are venturing into cable with half-hour projects at Showtime and TBS. Both shows, which are in development, hail from Kohan and Mutchnick’s KoMut Entertainment and Warner Bros TV/Warner Horizon, where the duo is under and overall deal. At Showtime, Kohan and Mutchnick are in negotiations for an untitled single-camera comedy project — an Upstairs/Downstairs dark comedy that centers on a self-made first generation American billionaire, his family, and the staff that serves them. This marks Kohan and Mutchnick’s first project at Showtime, reuniting them with the cable network’s entertainment president David Nevins. The pair credit Nevis with helping them get Will & Grace on the air as a development executive at NBC where he got behind the duo’s script. At TBS, Kohan and Mutchnick have Clipsters, an ensemble multi-camera workplace comedy set in a hipster barbershop in the not-so-hip town of Worcester, MA (just outside of Boston). The project was developed for TBS after meeting Kohan and Mutchnick took with the network’s programming chief Michael Wright.
