Has anyone discovered the easter egg?

I'm only posting this because, to my knowledge, no one has commented on it yet, and I only found out about it recently myself (by reading about it on another forum). There is a hidden special feature on this DVD. If you push the right arrow button on the commentary feature it turns off the commentary by Dana Polan, but if you push it a second time you will notice it highlights Shack's hammer in the picture. Push the play button and you get the original theatrical trailer for the initial release when it was known as "Emperor Of The North Pole", before it was changed to just "Emperor Of The North". In the initial trailer it says this movie takes place in 1931, as opposed to 1933 when the film says it takes place. Just thought I'd pass that along to anyone who hadn't discovered it yet.
