''As polished and perceptive a biography as you would hope from a writer who has done justice to Fellini and Bunuel.'' New Statesman & Society Steven Spielberg is one of the cinema's greatest enchanters, with a spellbinding capacity--and a box office record--matched by very few. His power now exceeds that of the greatest moguls of Hollywood's golden era, and films like the Indiana Jones trilogy, ''ET,'' ''Close Encounters of the Third Kind,'' ''Jurassic Park,'' and the Oscar-winning ''Schindler's List''--seen by billions around the world--have forever changed the way movies are made. How was it that this ''movie brat'' became one of the most formidable players on the global entertainment scene? John Baxter has applied considerable scholarship in his quest to discover what makes Spielberg tick, and it is a success story that he tells with relish. Now in paperback, with a filmography and 55 photographs. John Baxter is a film critic, novelist and biographer; among his many books are Bunuel, Fellini, The Hollywood Exiles, and The Cinema of John Ford. 460 pp 5 x 8 55 b/w photos
