Warner Home Video is set to release Harry Potter and the Goblet of Fire on March 7th. Early details have the two-disc DVD including a commentary with director Mike Newell (a first for the Potter DVDs), deleted scenes, behind the scenes featurettes, set-top games and activities - including the Triwizard Tournament Challenge - and more. Incidentally, Warner Brothers has hinted that they'll revisit the previous three films in the future to include commentaries plus other goodies for the adult fans!
