Five of my favourites, in no particular order:
Au Revoir Les Enfants (a superb French film/movie set in a Catholic boarding school during WW2);
The Third Man (a timeless classic, the story, the setting, the music, the cast, the cinematography, the characters, the script, that wonderful ending with the courage of its convictions, an example of the bittersweet integrity of art....);
Jesus of Montreal (an outstanding French-Canadian film/movie, an extraordinary and ferociously intelligent take on - interpretation of - the life of Christ);
Lone Star (an exceedingly good, complex, layered, thoughtful - and intelligent - US movie from the 1990s, John Sayles at his best);
Kind Hearts and Coronets (Ealing Comedies at their satirical best - I never tire of this movie; while the movie is possibly best known for the many roles played (hilariously) by Alec Guinness, for me, Dennis Price - with his dry, sardonic delivery, - is what makes this movie).
