Non, je l'ai pas vu.
This scene takes place in the middle of the film. The protagonists are under the influence of ether which makes them act stupidly. As they head for the entrance of the circus, they're completely dazed. They're having hallucinations. Some of the hallucinations are very powerful and scary. It's a very pathetic and ridiculous scene. Both men are staggering towards the entrance, and everyone around them appears to belong to carnival of strange beings. In reality, everybody is looking at them with puzzlement. The scene that follows is kind of blurred, and the viewer doesn't really know if what he sees is real or is simply the effect of the psychedelic experience they're both having. For example, the character played by Johnny Depp takes a drink at the circus bar which seems more like a merry-go-round than a bar. It keeps spinning around and around, and they can't seem to get off.
