No, the movie hasn't been confirmed for a release outside Japan yet, and as such, no DVD version is available in english.
There is an animated animal crossing movie, and you can watch it on www.youtube.com, but I'm not sure if it's available in english. It is about 90 minutes long, give or take a few minutes, and is quite good. I recommend it.
As Far As I Know Their Is Only One Song With Lyrics Whitch Is K.k Sliders Song. You Can See The Lyrics By Watching The Animal Crossing Movie In Japineese. But It Has English Subtitles. You Can Find It On Youtube.
Nope.
They're not releasing it in english. there's a half-way done fandub on youtube. not sure if they'll finish it though.
Animal Crossing New Leaf. It's coming out around May in English.
Spirited Away, or Animal Crossing The Movie
It was made after the game.
It is based on the idea as a Whole rather than one game. As I understand it though currently it's only in Japanese.
She is a cute blue cat that appears in all Animal Crossing games. She even appeared in Animal Crossing The Movie and is Ai's friend!( But her name in Japanese is Buke, pronounced like bouquet!!)
Animal Crossing 3DS
No, there isn't a website to play animal crossing. Animal Crossing is a paid-for game, not a game that you play online for free. Nintendo would lose too much money, so it is a paid-for game, and it's too popular not to be sold at stores.
you can watch a certain amount on youtube but when it comes out on DVD i recon you will have to look for it on e-bay or something(the closest place i think you can get it is china).
