Casshern director Kaz Kiriya's next film - the fantasy epic Goemon - may be tied up in a lengthy post production process right now but that's no reason not to be keeping tabs on it. Kiriya has proven to be a remarkably open director when it comes to letting fans look behind the curtain and in keeping with that a series of behind the scenes videos has been uploaded to the official Goemon website to let fans get a look at the process. There are eleven of them there so far and more coming all the time.
