Both were originally released on DVD in November 1999. The first edition of Chinatown featured an anamorphic transfer, the original mono track, a remixed DD 5.1 audio version, the theatrical trailer and retrospective interviews with Nicholson, Polanski and producer Robert Evans. The forthcoming edition promises a restored mono audio track and four featurettes. Given the advances in DVD technology and the years since the original Chinatown transfer was completed, remastering the video would seem a given -- and would justify a double dip -- but no mention of a new transfer has been made.
The first DVD edition of The Two Jakes was even more bare bones: it had just the theatrical trailer in addition to the anamorphic transfer. The new "Special Collector's Edition" adds one featurette: "Jack on Jakes." Frankly, I'm having a hard time seeing how the new releases will be either special or collectible. The Two Jakes is strictly a curiosity item; a rental would suffice. But Chinatown is a classic; it rewards multiple viewings and deserves the deluxe treatment, which it evidently won't be getting anytime soon from Paramount.
