Well, as we sit around waiting for Sony to release
Das Boot on blu-ray in the US, I found a website that compares 10 shots from the 1997 DVD with the 2010 German blu-ray. Just click on "1920 x 1080 fullscreen comparison."

Wow. A bit like watching the movie with glasses on. I hear Sony is working on a new master, so let's keep our fingers crossed!
