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 bestselling novel by Lothar-Günther Buchheim, Petersen and his committed cast (led by the amazing Jürgen 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.

On the DVD: The 200-minute "Director's Cut" version of the movie not only has several major scenes restored that were not in the theatrical release but also has been digitally remastered with significantly improved sound (new sound effects have been added) and anamorphic picture. (The six-hour TV version has yet to be released.) Here, the viewer can watch the movie in the original German, with or without subtitles, or in an English dubbed version that uses the voices of many of the original cast. On the utterly engrossing commentary track, director Wolfgang Petersen and star Jürgen Prochnow talk animatedly and in great detail about every aspect of making this epic story--from model shots using Barbie dolls to meeting the Captain of the original U-boat. This is one of the most consistently rewarding commentaries on disc. Also included is a five-minute featurette that promotes this new version. --Mark Walker

Inspired by a famous 1971 psychological experiment, Oliver Hirschbiegel's German-language movie Das Experiment finds a group of 20 volunteers randomly divided into 12 prisoners and eight guards and asked to play out their roles for a fortnight while scientists study their reactions. A conflict arises between undercover reporter Fahd (Moritz Bleibtreu), a con with a hidden agenda and the apparently mild-mannered Berus (Justus von Dohnanyi), a guard with a megalomaniac streak. The film begins as a psychological drama as ordinary people settle into the game, with joking displays of resistance by the "prisoners" greeted with increasing brutality from the "guards", but detours into suspense and horror as Fahd, who needs the experiment to get out of hand in order to make his story more saleable, deliberately ratchets up the tension between the factions only to see the situation spiral nightmarishly out of control as various test subjects in both camps edge closer to snapping.

With a terrific display of ensemble acting and unforced use of the currently popular claustrophobic semi-documentary look, Hirschbiegel's movie takes its time to get underway, with apparently irrelevant cutaways to Fahd's outside girlfriend (Maren Eggert), but works up to a powerful second half that delivers a sustained symphony of psychological and physical anguish.

On the DVD: Das Experiment on disc has an excellent-looking anamorphic widescreen transfer with English subtitles. The only extra feature is the trailer. --Kim Newman
