My recommendation is to rent or view or buy it to get a view into this jewel.
It is a german made anti war film in pure german setting and even the ending works well, not always true with anti war attemps. Ie. The Dictator which is still great.

It is reworked by every possible manner in image and sound dvision and re edit to "Directors Cut" for re-issue in 1997.
And, it is lovely to not be "stuffed" with heroism and muzak through out the film as is so common nowadays.


Recommended.
And while there look for "The Marriage Of Maria Braun" by Fassbinder.When DAS BOOT was originally released in the U.S. in 1982, the film's enormous success was a surprise. A sub-titled German war movie a hit? It sounded absurd. And yet the astonishing level of filmmaking and deeply felt anti-war message gripped audiences to their chairs as they witnessed the never-before-seen story of German U-boat soldiers riding the bottom of the ocean.
DAS BOOT forever changed audiences' expectations of unrelenting tension and visceral authenticity in an action film. DAS BOOT set a new standard for high-wire suspense and broke fresh technological ground. It also became the most successful foreign film ever released in the United States Ñ nominated for six Academy Awards and shattering box office records Ñ and continues to be one of the most popular foreign films on the video shelves.
Now a new generation of moviegoers will have a unique opportunity to experience the director's "ideal" cut of DAS BOOT in the theaters Ñ complete with newly added footage and re-designed digital sound that bring this action classic to state-of-the-art standards for today's audiences.
