I have limited training in film studies, but I appreciate that foreign-language films elucidate cultural and linguistic nuances that students might not encounter otherwise. Even if films are fictionalized, there are grains of actuality. As I watch movies, I will make a note here and then elaborate on some of the movies in other posts.
This list is just films that I have seen. I pick movies based on their availability rather than on a process (like searching by theme, setting, or genre). I welcome recommendations!
