Take the following as truth: Biskind's book, accordingly, concludes with a litany of spectacular  Coppola's Apocalypse Now and One From the Heart, Spielberg's 1941 , William Friedkin's Sorcerer, and, of course, Michael Cimino's Heaven's Gate . According to Mardik Martin, Scorsese's erstwhile writing partner (as quoted by Biskind): The auteur theory killed all these people.
Then the following statement: "Biskind stated that Mardik Martin had been William Friedkin's former writing partner." is true, false, or inconclusive?
Answer: True
