I'm obviously culturally off, but usually my Christmas movies are:
Love Actually
Chocolat (not really themed, but I love the warmth about it)
...and a bunch of Czech and Slovak ones that you never heard of, with
Three Wishes for Cinderella as my top one ever (and my top fairy tale adaptation ever, too, it's beautifully non-sentimental, fun and winter-mood-ish). It's pretty famous, so maybe it's even available in the US. It's truly worth it.
