The DVD company 2|Entertain has announced that the release of the classic Third Doctor story ‘The Ambassadors of Death’ has been delayed due to issues with restoration. It was originally planned for the story to be released along with the Fourth Doctor story ‘The Sun Makers’, however it will now not be released until 2012.
The story only survives in the BBC Archives with the first, fifth and sixth episodes in colour, and the other four parts in black and white. The colourisation technique used to restore Episode Three of ‘Planet of the Daleks’ in 2009 is being used to colourise the remainder of the story. Unfortunately this process is taking longer than predicted, which has caused the release date to be put back until next year.
