"But the most remarkable are the actors , all more or less unprofessionals who behave with an ease as if they were playing themselves, and who make us immediately experience this combined joy of acting and being."

Excellent point! Doillon has a knack for drawing out the most naturalistic performances from his cast (Ponette is perhaps the best example of it).

"The film reminded me a bit of Pasolini's "Theorema", through the enigmatic visitor who heightens the characters awareness to another level and enriches their lives. But even more it seemed like a reworking of Eustache's "The Mother and the Whore" that had come out a year earlier, especially regarding the camerawork that seemingly locks the characters in their own world"

Interesting. I didn't think of it that way, but it's been a while since I've seen Les doigts. Though Doillon, who could be referred to as a poor man's Garrel (no harm if you don't know what I meant), has spoken highly of Eustache on various occasions.

(Btw, if you're planning on reviewing more of his films then perhaps a thread in the director's forum is needed. I'll move my review also. Keep it up!)
