Actually, the film is woefully inacurrate. Ian Kershaw was originally involved, but disassociated himself from the project due to glaring historical errors and genuine make-believe on the part of the writers.
And it was Himmler that was totally omitted, not to mention to complete lack of attention given to the roles Goering, Goebbels, Eckhart, Strasser, and Schleicher played in Hitler's rise; most of that gets attributed to Ernst Hanfstaengl, a relative nonentity.
That aside, it was a fairly entertaining movie. Robert Carlyle was quite good. Peter O'Toole was excellent as the doddering, indecisive Hindenburg.
