has anyone seen this? it's by christoher nolan, the god who gave us memento, but this predates that. i saw a chunk of it and it was like memento on crack. the entire film is black and white and there are 4 different time frames going on so there's no way to differeniate between 3 of them at least 1 the main character has a beard. if someone has seen this, i'd like to know if it's worth renting cuz when i saw parts i was totally confused.
