1) Pan's Labyrinth (Spain) - it moved me to tears, and not many films can do that to me. Just the music alone makes me want to cry. It's such a beautiful film and it's something that I always recommend to others.
2) La Lengua de las Mariposas (Spain) - this is another film which I love. It's truly a masterpiece, showing life before the Spanish Civil War. It's a beautiful film showing the innocence of children.
3) El Orfanato (Spain) - a clever film that made me think.
I'm a language student, so most of the films I watch are French and Spanish films. Honourable mentions go to La Haine, Mar Adentro, Y Tu Mama Tambien, Volver and Le Scaphandre et le Papillon (very moving film).
