Much more like Das Boot this time....

[Subnuts]

While Das Boot is probably my favorite war movie of all time it's best to remember that, despite being the most "accurate" submarine movie, a lot of is either dramatized, "enhanced," what have you, for cinematic effect. Also, real U-boats were painted white inside and weren't lit like caves. I imagine Petersen and co. were trying to recreate the look of Buchheim's photographs, which were dark and high-contrast by nature, but that's not how it was in real life.
