EXCLUSIVE: The last time Paul Reiser created a sitcom that was picked up by NBC, it was the major hit Mad About You and ran from 1992 all the way to 1999 on the network. So it’s understandable if NBC is feeling somewhat nostalgic for Reiser’s product. Now I’ve learned that last night the network picked up a Warner Bros pilot that was written by and stars Paul Reiser who also will executive produce. There’s no official announcement about this yet. But the deal for this single-camera filmed series is said to be “big”.
