[DOC] [TLE] HBO developing F. Scott Fitzgerald's The Last Tycoon as a series ... [PAR] Nov 19, 2013 ... F. Scott Fitzgerald wrote in the notes for his unfinished final novel ... Elia Kazan 
previously adapted the novel as his last film in 1976, with a screenplay by Harold 
Pinter .... Not that those elements wouldn't make for a good series, but just ... such 
a shame he didn't live long enough to finish The Last Tycoon.
