Doctor Who - The Ark In Space [1974] [1963] - Region 2 DVD

On the DVD: "The Ark in Space" DVD's obvious highlight is an audio commentary track featuring Tom Baker, Elisabeth Sladen, and producer Phillip Hinchcliffe. Though Baker's contributions to the track are sporadic, his participation is valuable nonetheless, considering that his involvement with the series since his 1981 departure has been infrequent at best. The full-frame mono presentation also includes two interviews, one with Baker on the set of another episode in 1975 and the other with designer Roger Murray Leach, who discusses his long involvement with the series. Also included is the episode's BBC1 trailer, an unused title sequence, new CGI special effects produced by the BBC's visual effects department and an optional information track, which provides running background information and trivia that should prove valuable for series completists. A trio of Easter eggs reveal Baker's typically eclectic promotions for the Doctor Who exhibition in Blackpool. --Paul Gaita, Amazon.com
