In other sci-fi news, Warner Brothers Home Entertainment is preparing to release a whole batch of Doctor Who releases over the next few months.

First up in August are two separate special editions releases:

Doctor Who: The Tomb Of The Cybermen: Missing from the BBC archive for more than 20 years, all four episodes of this story miraculously resurfaced in Hong Kong in 1992. The Second Doctor (Patrick Troughton) visits the planet Telos with his companions Jamie (Frazer Hines) and Victoria (Deborah Watling). There they encounter a party of archaeologists who cannot be dissuaded from excavating a tomb of the extinct Cyberman race.

The features on the disc include an audio commentary from Frazer Hines and Deborah Watling, behind-the-scenes featurettes, a trailer, pop-up production notes and a photo gallery.

Doctor Who: The Ark In Space: The Fourth Doctor (Tom Baker) brings Sarah Jane Smith (Elisabeth Sladen) and a very skeptical Harry Sullivan (Ian Marter) thousands of years into the future to a space station that holds the future of humankind in suspended animation.

The disc will contain an audio commentary from Tom Baker, Elisabeth Sladen and producer Philip Hinchcliffe a trailer;, pop-up production notes a photo gallery, unused model footage an interview with Tom Baker and designer Roger Murray-Leach and new CGI model footage.

Then in October come all six volumes of the “The Key to Time” series.
