Josh Hartnett, Demi Moore, Woody Harrelson, and Ron Pearlman are going to be in a movie called "Bunraku" with Gackt. I have a thread about it in the movie section if you want to know more.
I agree that Gackt's music is a bit overrated. I think that he is a really interesting person and I love his Malice Mizer days. I love to watch him on shows and commercials, but I do get bored quickly with his music.
Oh, here is a HILARIOUS video of Gackt vs Hyde I found last night! A fan did this and a did a wonderful job! It is to "Anything you can do, I can do better", and it is so FUNNY! Check it out!
