Product Description: 
A Great Cast… A Great Novel… A Great Motion Picture! This 1949 retelling of F. Scott Fitzgerald’s beloved novel takes us back in time to The Roaring Twenties, an age of hot jazz and cold champagne. The great Alan Ladd (Shane) stars as Jay Gatsby, formerly Jake Gatz, who works his way from poor fisherman to extravagant Long Island millionaire and then risks it all to woo back his former love, the beautiful Daisy Buchanan (Betty Field, The Shepherd of the Hills). Shot with noir style by director Elliott Nugent (The Cat and the Canary), this rare and ravishing Paramount adaptation was made long before the book became canonized as The Great American Novel. The first-rate cast features Macdonald Carey, Ruth Hussey, Barry Sullivan, Howard da Silva, Ed Begley, Elisha Cook Jr. and Shelley Winters.
