Muriel is a riddle. It may just have been the first art-house movie I ever saw. It was on local TV one day when I was about 18 maybe and I left it on because I was studying French and had been told to watch French movies. I found myself amazed and dumbfounded by the jump-cuts and seeming lack of continuity between scenes.
Today, 12 years later or so I've finally seen the whole thing and I feel like I saw a completely different movie to the one I saw last time. I feel I understand who the characters are, what the central mystery is, but I understand very little of the minute by minute goings on of where characters are moving and why. I feel this is a film that intentionally tries to disorient you constantly. Just as you are becoming comfortable in a scene, it will switch completely and never return. It reminds me of a perfectly normal film about four characters and their interrelations that has been sliced up and then recreated anew in the editing room. The characters make reference to dreams and memory, but on this viewing I didn't see it as necessarily a recreation of those things, but as a depiction of disorientation.
I found the newsreel section in the middle, which I don't at all remember seeing 12 years ago, particularly important addition, and the whole thing is just as refreshing as it ever was.
