The Paper Chase - Season 1 - Eps 21: A Case of Detente
Although this was not the last episode shown, as the production numbers tell, it was the last one produced. I remember that the last episode was about Hart falling in love with a Russian gymnast. John Houseman did not appear as Kingsfield in this episode. I heard that, because the network had caused the scripts to be ""dumbed"" down to this level, that Houseman refused to be in it. A visiting professor played by Pernell Roberts had to help Hart with his love life. I also understand that Houseman refused to do the Showtime seasons unless it was understood that this episode would never be reshown.
