Despite overwhelmingly positive critical reviews, Children of Men lost money in its 2006 theatrical run. Most people I knew had never heard of it, and the only person I knew who had seen it was the friend I went to the theater with. It's now generally regarded as one of the best films of the 21st Century (so far) and particularly lauded for its cinematography. It's had a very successful home video run since then and is even more relevant today than on its release.
