The Disney Channel ran a quick preview of Pirates Of The Carribean:At World’s End. You can find it on youtube, of course. I wish the picture quality was better. Still you get to see Johnny Depp returning in his role as Captain Jack Sparrow. So it’s not all bad.
I don’t know why Disney doesn’t release this stuff to youtube themselves, they have a bunch of podcasts that is perfect for this stuff. Perhaps they will with the new Disney.com makeover.
