 The movie "To Kill a Cop" was not planned as a series, and only  became one at the last minute. TV Guide reported that NBC  programming chief walked out of a screening of a pilot called "Two  Guys From Muck" (developed by Brandon Tartikoff) before the show  ended and expressed colorful displeasure with that show and others  on the 1979 NBC fall schedule, forcing Tartikoff to spend three days  in negotiations with To Kill a Cop producer David Gerber to develop  a series around the lead character.
