Has anyone seen the short film "La Femme qui se Poudre"? It looks creepy.
Yes, I have seen both, and in fact I could recommend other Conrad Veidt films
, as well as "The Cabinet of Dr. Caligari". Nosferatu is a bit overrated for me (although I adore that type of films), but surely you will like it, so watch it too.
There are very good movies: Orlacs Hände, Sunrise, Der Gang in die Nacht,
Vampyr, Dr. Mabuse, Phantom, Faust, Der Letzte Mann, Der Student von Prag, etc ... But start with Caligari, it's wonderful.
But surely
@lgorTudor can recommend you better movies.
