Rejoice, Todd Margaret fans: David Cross is developing a comedy at Showtime. Cross tells Deadline that the show is about “a modestly successful travel writer who struggles to keep his families happy and satisfied. Oh, and also from finding out about each other’s existence.†Apparently Cross would not play the lead guy but might play a supporting role. Despite several tries (House of Lies, Episodes), Showtime hasn’t quite found another comedy to break through the way Weeds did in 2005, and certainly nothing that’s been a hit the way Dexter or Homeland has. No offense, Nurse Jackie.
