The movie was only INSPIRED by the short story which was virtually DIFFERENT in almost every way. Outside of that, Chris completely wrote and directed a COMPLETELY different story with a completely different character in a completely different setting, hence it being a completely ORIGINAL film, especially in the WAY it was told in reverse and forward at the same time. ZERO input from Johnathan Nolan.
There were only TWO Nolan films that were nominated for best screenplay, Memento and Inception... NEITHER having Johnathan's involvement film-wise. So I stand by you don't know shyt about a great film if it sodomized you...
