The twenty-first issue of The Doctor Who DVD Files was released today, and is now on sale at good newsagents across the United Kingdom and Ireland, being sold at the price of £6.99. This fortnight's issue comes with the final episode of Doctor Who series three, Last of the Timelords, and the 2007 Christmas special, Voyage of the Damned, on DVD. The magazine features episode guides for the episodes included on the DVD and takes a look at the Toclafane, the Star Ship Titanic, Ace, the actors who have played past incarnations of the Master, and the Ter-trap, The Rani's bat-like servants. Inside, you can also read about the end of an era, when Sarah Jane Smith had to depart from her adventures in the TARDIS. The twenty-second issue of the magazine will be released in two weeks time, and will include the first episodes of Doctor Who series four, Partners in Crime and The Fires of Pompeii, on DVD, and will include guides to both episodes.
