Colony in Space was the 4th Master story in a Master-full season, this story features Jon Pertwee's first off-world adventure in the TARDIS since The War Games, it's a 6-parter and as such, this story does suffer from a little padding, but only a little. As stated above, this is Jon Pertwee's first trip into space as the third doctor, also note that this is the first time Jo Grant ventures into the mysterious blue box, as she enters, the usual words come to mind {bigger on the inside}. However, she displays genuine fear that the Doctor was actually telling the truth about being an ancient alien Time Lord who travels around in time and space in a police box.
The relationship between the Doctor and Jo definately strengthens throughout the story as she comes to terms with the reality of the situation. This is played very well by Katy Manning. Shame really, the Master is introduced in the fourth episode and was only brought in to keep the story running for another couple of episodes. I.M.C. is a great evil-corporation villain and really brings a sense of danger to proceedings. Caldwell is brilliantly played by Bernard Kay in his last apperance in Doctor Who. Generally, Colony in Space is a brilliant start to Jon Pertwee's "mission for the Time-Lords" series of stories.
Now then, on to the DVD, yet again the BBC, 2-Entertain and the restoration team have done a wonderful job in restoring this classic serial for DVD, it is a budget 1 disc release and is light on special features but does the job admirably, the documentary I.M.C. needs you is a typical making of doc about the production, but, as usual I find these things very interesting and find they add to the experience of the feature itself. Please note that because the master tapes were wipped by the BBC for reuse in the 1970s, the episodes have been returned from canada, the picture is not as great as stories with masters held in England, but it does not detract from the programme.
All in all, Colony in Space is a fine edition to an ever growing selection of Doctor Who DVD's being released now-a-days, so go ahead and order this Pertwee classic and enjoy some vintage haircuts.
