In 2004, all known surviving clips were released on the DVD set "Lost in Time". Following this, two further short clips – along with a higher-quality version of one of the extant scenes – were discovered in a 1966 edition of the BBC science series "Tomorrow's World"; these clips only came to light on 11 September 2005, when the relevant section was broadcast as part of an edition of the clip-based nostalgia series "Sunday Past Times" on BBC Two. They were subsequently included in the documentaries "The Dalek Tapes" (on the DVD release of "Genesis of the Daleks") and "Now Get out of That" (on the disc containing "Terror of the Vervoids", within "The Trial of a Time Lord" box set).
