This review will be spoiler free, so if you haven’t watched the film feel free to read on without worry.
I recently picked this up on sale at Best Buy for $10, in one of the very rare instances when Best Buy had a better price than Amazon.
The movie stars Guy Pearce playing a man who has a special form of memory loss that prevents him from forming any new memories. The film was written and directed by Christopher Nolan, whose talents you may have enjoyed in Batman Begins and Dark Knight, and possibly in opposition to the Jo(h)ns running this site: The Prestige.
The film moves backwards. I remember having rented this once before and the disc was scratched or something and so I missed the beginning of the movie, which is really the end, so I was fairly confused for most of the flick. Anywho, I bought it because I remembered enjoying the parts I did see and finding it a very novel way to tell a story (partially the reason I enjoyed A Scanner Darkly).
Our protagonist, Leonard Shelby, is still reeling from the loss of his wife whom, according to his tattoos, was raped and murdered by John G. He is still reeling from this, because that is the last thing he can remember, which serves to fuel his desire to find and kill John G.
In summary, definitely worth a watch, and possibly a buy.
