Final Paper Rashomon

I'm planning on doing my final paper on the 1950 film Rashomon, directed by Akira Kurosawa and written by Shinobu Hashimoto along with Kurosawa. The film takes place in 12-century Japan and follows three different accounts of the murder of a Samurai, as told to a trial judge. Each account, - the first from the killer, the next from the slain samurai, and the last from a third party - are each completely different from each other. Yet, as Kurosawa presents each story with equal credence, he challenges the viewer to decipher which is true, if any of them are. I'm planning to relate this to Sobchack's idea concerning memory.
