Another favourite I forgot!
Amelie was the first movie that came to mind. It’s generally not considered with the arty films of this genre, but I liked Trollhunter a lot.
The first one that came to mind was Seven Samurai, closely followed by Rashomon.
Same here.
Far too many to choose just one! I love Au revoir les enfants, The Lives of Others, Open City, Cache, Son of Saul. And many others.
As for Russian films, which is the category of “foreign” films that I have seen most of, some of my top choices are Wings, We’ll Live until Monday, The Cranes Are Flying, The Ascent, Ivan’s Childhood, The Italian, How I Ended this Summer. My favorite contemporary Russian director is Andrei Zvyagintsev. His films The Return and Elena are magnificent. His most recent film, Loveless, is also outstanding. I saw it last summer in Russia but I think it is playing in the US now (at least in some locations).
Das Boot
Ran
Rashomon
Seven Samurai
are my four faves. Good list. I have never seen- or even heard of “Betty Blue” sadly.
Betty Blue. Find the theatrical release. While the Director’s Cut gives it more depth, it kind of drags. The theatrical release is better, in my opinion.
Funny thing about this film. I met this girl, and we decided to see it on our first date. It starts out with a very explicit sex scene. I was thinking she might be thinking that I took her to this film to get her ‘in the mood’. :eek: :smack: But she liked the film. I have the soundtrack.
I think you should see it (the theatrical release) before reading the spoiler, even though it doesn’t give away the ending. The spoiler relates my emotional reaction upon seeing the film, and I think the film should be seen before reading how I felt.
Betty Blue started out funny. Then it was cute and funny. And then it was tragic. I was like, 'What? OMG! 
’
In that last , Kinda sounds like Shultze Gets the Blues, which I liked and could be considered a Foriegn language film (tiny bit of English, mostly in German)
I’ve always been curious about playing with egg yolk, but I’m too easily squicked out to try it.
My favorite is still My Life as a Dog. It just gets better for me every time I see it.
I know, I’m pretty vanilla. Wait…do Lord of the Rings movies count?
Actually, I believe it is - those are the English and French terms for the technique for filming in daylight to make the audience think it’s night.
I would go for a Jacques Tati, but it’s mostly either non-verbal humour or partly English dialogue. As for which, I’d go for Jour de Fête, Les Vacances de M. Hulot, and Mon Oncle over the others.
And Les Triplettes de Belleville (Belleville Rendezvous)
Rashomon and Akira in Japanese.
Anything by Trueba in Spanish (hey, it’s foreign for you guys).
Back when the world and I were young, A Philadelphia Story and Sergeant York got a lot of mileage on Saturday afternoons when there was nothing on TV (hey, they’re foreign for me!).
I want to watch a Tati film right now. Playtime for first choice.
Les Triplettes de Belleville was enormous fun.

And another one!
Peter Lorre whistling In The Hall Of The Mountain King. 
Does it really count as a foreign-language film if there’s only a single throwaway line of diegetic dialogue?
Amelie and The Lives of Others
Playtime is one of the greatest comedies every made – if you see in 70mm on a full movie screen. Otherwise many of the dozens of jokes per minute are lost.
After that, I’d go with The Tall Black Man With One Black Shoe.
For drama
Children of Heaven is pretty powerful
Osama has one of the most horrifying endings in the history of film.
Luis Bunuel’s El is a fascinating portrait of sexual obsession.
Isn’t the theme song in French?
A lot of my favorites listed here, I’m surprised no one’s listed Spirited Away yet.
