 According to the 1973 book "Marilyn Becks Hollywood", when  Pernell Roberts (qv) told Lorne Greene (qv) he was leaving the  series because he wanted to challenge himself as an actor, Greene  told him to stick to it as he would be so rich by the end of the run  he could hire Tennessee Williams (qv) himself to write a play for  him. Roberts career went into a tailspin that lasted over a decade  after he left the show. Co
