As of now, Paramount has said that it will release Sweeney Todd: the Demon Barber of Fleet Street on DVD and HD DVD on April 1st, 2008.
A simple, one-disc version of the film will be released that day, as well as a two-disc collector's edition packed with bonus materials, both on DVD and HD DVD. No box artwork or special features information has been released yet.
However, Paramount has not responded to Toshiba's decision to discontinue the production of HD DVDs, in favor of its rival technology, Blu-ray. Whether this will affect the release date of the Todd DVD has yet to be known.
