What a Producer/Director/Writer ! The Odd Couple , Happy Days , Laverne & Shirley , Mork & Mindy , Joani Loves Chachi ! And many great holiday romance movies ! He has a son , Scott Marshall who is a Director and seems to have the same sense of humor too ! There is no one to compare , but I am also a fan of Nia Vardalos who is a Producer/Writer and does similar movies .
