I wondered the same thing, Lemur, but then noticed the period restriction 1951-64 in the OP. It's a rather short period and I am curious as to why those particular years, rather than any others, but King Louise can't be said to have missed films outside it.

One question to King Louise or anyone else, though: are those 12 films good, do you think? I really like Spartacus, if more for a depiction of the world as I would like it be rather than as it actually was, and think it is a great movie, as well as a great historical movie. Some of the others, I can take or leave - they are made with a certain grandeur, but I am not sure they stand up in contemporary times as good drama or history. Others I am unfamiliar with. Are there particular ones people would recommend?
