i live in Australia but i got the dvd off Ebay since its not released here for 2 months!
They're alright..you've got some featurettes about filming the big sequences (Happy working song, that's how you know and the ballroom ending), bloopers, deleted scenes and a short 'Pip's pop-up' adventure. They advertise the Blu-Ray (D-files) and it looks so good if only i could afford a blu ray player.
Apparently for a limited time, you can get a bonus disc of special features at Target when you got the dvd, from what i've heard, people like these features better than the ones on the dvd.
