For those of you who doubt Ethan's involvement in these films, check this out:

I live in the Chicago area, and one of the most popular morning drive shows is the "Eric and Kathy" show on 101.9 FM. One of my friends, knowing about my interest in this movie project, happened to hear an interview with Ethan Hawke on this show. Ethan said that he was going to be involved in a three-movie project in the near future. He supposedly did not name any roles, but since his name has been bandied around lately regarding the Lord of the Rings project, I thought you might like to know.

Very interesting...Will find out more soon :)

Thanks to The Glaze for the tip!
