"Planet of the Dead" was the first Doctor Who episode to be filmed and broadcast in high-definition. It was released on Blu-ray on the same day as its corresponding DVD in Region 2.

An upscaled version of "The Next Doctor" (which was shot in standard-definition) was also released on Blu-ray as part of a box set containing all of the 2008–10 specials. It was also released individually in Australia and New Zealand. In 2011, the 1975 Doctor Who serial Pyramids of Mars was included on both the DVD and Blu-ray box sets for The Sarah Jane Adventures Season 4.
In October 2012, its was announced that Spearhead from Space would be released on Blu-ray sometime in 2013 with exclusive bonus features.
