The 1984 (UK) and 1985 (GermanyAustria) TV mini-series was three 100 minute episodes. Edited for DVD (2004), the mini-series is 293 minutes. The original theatrical release (1981) was 149 minutes. The 1997 "Director's Cut" version (cut by director Wolfgang Petersen) is 209 minutes. They are all the same movie, filmed 19791981, but edited differently. Wolfgang Petersen wanted it to be a five hour movie. The 209 minute version, released in 1997, was Petersen's rejected cut for the 1981 theatrical release.
The actors were all bilingual and did their own English dubs. IMO they were better actors in German than in English, and I recommend watching it in German if your screen big enough for reading subtitles.
The Region 2 (European) version of "Director's Cut" is the only DVD release with German subtitles very helpful to German language students.
The movie is based on a 1973 novel
Das Boot by Lothar-Günther Buchheim. Buchheim was a war correspondent on the U-96, like Lt. Werner in the movie. He hated the 1981 theatrical release, which wasn't anti-war enough to suit him. He called it a "cheap, shallow American action flick," but he lived to see the 293 minute DVD and he liked that.
Heinrich Lehmann-Willenbrock, first of U-96's five captains, and U-219's first officer Hans-Joachim Krug were consultants during the film's production.
The movie Captain's favorite song was Rina Ketty's "J'attendrai."
