Just saw this Carax film a while ago and loved it. He's one of my new favorites. It's inexplicable at first, but if you watch the whole thing, it really is a tribute to actors and what they have to go through.
I really can't in good conscious give anything in this movie away. But I is this the scene where he does the thing and then goes to that place? Because OMG that place where he does that thing is just wow.
Oh, also, you'll need to have a movie buddy to watch this movie. It's one of those films that require it.
Mr Merde is awesome...he is actually also in an earlier movie called "Tokyo", where 3 french directors each do a weird story about Tokyo. You can watch the entire Merde chapter of that movie on this vimeo link: http://vimeo.com/5851763
