New Line has announced that they will be bringing the remake of the musical 'Hairspray' to Blu-ray on November 20th. Extras will include a new musical number, the documentary "You Can't Stop the Beat", a "Hairspray Extensions" featurette, audio commentaries and deleted scenes. The Blu-ray release will also feature a "Behind the Beat" picture-in-picture experience.
Update: According to an article at Home Media Magazine, most New Line releases, including this one, will be HD exclusive to Blu-ray for a limited time due to regional coding issues with the HD DVD format (HD DVD has no regional coding).
