To put Moby Dick, the enormous whale created by the pen of Herman Melville, on the wide screen had been an almost impossible undertaking until 1956, when John Huston's Moby Dick appeared. Twice the enterprise had been tried before he realised the film: first in 1925 with the title The Sea Beast directed by Millard Webb and in 1930 directed by Lloyd Bacon. On both occasions it had proved a failure because they had turned Moby Dick in a romantic story. On the contrary Huston, with Ray Bradbury's co-operation, struck on the right idea. They wrote a script as faithful to the novel as possible. In fact they caught the true feeling of the story, which is based on the ambiguity of the whale who shift from the physical to the metaphysical dimension. The difficulty of turning the masterpiece by Melville into a film is also proved by the long period that passed from the beginning of the forties, when Huston decided to realise the film, until the fifties when he was really able to do it. In Huston's adaptation, great importance is given to the first part of the story, which presages an unlucky voyage. Huston actualizes the ambiguous hunt for the white whale paying great attention to Captain Ahab's mad quest. This role is superbly played by Gregory Peck who perfectly embodies the brave, obstinate, blasphemous and damned captain. I cannot avoid of highlighting the brilliant starring of Father Mapple by Orson Welles and the very impressive Huston's Queequeg acted by Count Friedrich Labour.
