I wouldnt participate in a performances list personally.
While I love a lot of non-English movies, I dont feel remotely qualified to compare performances where the tones and idiosyncracies of speech are reduced to subtitles. Seeing people that Ive seen in a dozen performances (Ullman, Mifune, Gabin) makes it a little easier, but still.
Documentaries or Short Films would be fun. Or by decade top 100s or something like that.
