New York Times:
A rolling and thundering color film that is herewith devoutly recommended as one of the great motion pictures of our times.
One could have plenty of quarrels with this as an adaptation of the Herman Melville novel, but it's still one of the better John Huston films of the 50s.
Moby Dick is certainly the most unusual picture of the year and may well be the best.
Moby Dick is interesting more often than exciting, faithful to the time and text more than great theatrical entertainment.
