You know, The Lives of Others would be Die Leben der Anderer, die being the nominative plural. Das Leben der Anderer is literally The Life of Others, das being the nominative neuter singular, and I’ve been mystified by the idiomatic use of the singular since I first saw the movie, but it is the kind of question that would be answered with an eye roll and tone of annoyance, which would be all that much scarier in a German accent. So I say nothing and wonder in silence, which the Germans no doubt have a word for.
Great movie.
