Wolfgang Petersen's harrowing and claustrophobic U-boat thriller Das Boot was released as both a theatrical film and a six-hour mini-series, and remains the most expensive production ever made by a German studio. The expanded "Director's Cut" of the movie was re-released 1997 and it is this version that is available for home viewing. This epic story became an instant classic on its first release, provoking critical and audience acclaim worldwide for its sympathetic and entirely truthful portrayal of a German U-boat crew. Faithfully adapted from the best-selling novel by , Petersen and his committed cast (led by the amazing Jrgen Prochnow) were concerned to ensure that every detail was rendered with painstaking accuracy--both physical and psychological--and the result is not only the best submarine drama ever made but also arguably the finest cinematic portrait of men at war and the terrible madness they must endure.
