>The leg is used both as a urban legend that was told at the region at the time, but also as a metaphor. The surrealist scene where it shows the leg brutally attacking people at night: all the people attacked are prostitutes, gays, etc. People that during the dictatorship the police used to just dissappear, and society turned a blind eye to it.

Yeah, so I had to lookup the leg after watching the movie. My interpretation was that it wasn't actually really surrealism. They juxtapose that scene with the lady reading from the newspaper about the attacking leg as if it was real. The reason I think this supports the "from the future journalist's perspective" interpretation is that those were legitimate articles ran, while there were serious cases not being reported on things like people going missing by the dictatorship. I think they included it to show the absurdity of what information was available and what information wasn't in the papers from that time. Also because of the lore of it all.
