Using a trick we hope Gaspar Noé never gets around to with Irreversible, Christopher Nolan reordered Memento chronologically for the DVD release. If there's something strange about seeing the twisty-turny plot threads straightened out, like hanging spaghetti neatly from a washing line, watching the narrative unfold in linear fashion emphasises how darn clever it is in the first place. Nolan provides something similar on the Following extras package. Clever clogs who 'got it' first time round would have probably skipped this, but for those that didn't they're as handy as his Batman DVD commentaries are enlightening.
