The End of the World (Doctor Who)

"The End of the World" is the second episode of the first series of the British science fiction television programme Doctor Who. Written by executive producer Russell T Davies and directed by Euros Lyn, the episode was first broadcast on BBC One on 2 April 2005 and was seen by approximately 7.97 million viewers in the United Kingdom.

In the episode, the alien time traveller the Ninth Doctor (Christopher Eccleston) takes his new companion Rose Tyler (Billie Piper) five billion years into the future where many rich alien delegates have gathered on a space station called Platform One to watch the Sun expand into a red giant and destroy the Earth, but the human guest Lady Cassandra (Zoë Wanamaker) is plotting to profit from the event by fabricating a hostage situation.

"The End of the World" is the first episode of the revival to be set in the future. Due in part to the numerous SFX shots, the episode used up most of the series' SFX budget. The episode also features numerous intricate costumes. Location filming principally took place in Cardiff in October 2004, with some additional scenes shot in Cardiff and Penarth in November 2004 and February 2005. Studio work was recorded in the Unit Q2 warehouse in Newport from September to November 2004. The episode marked the first appearance of Cassandra and the Face of Boe, both of which would appear in the series two episode "New Earth". This was also the first episode of the series to include mention of the phrase "Bad Wolf", a recurring arc throughout the first series that would set up the events of the finale.
