The Steward of Platform One recognises something is wrong, but is killed when the spiders lower the solar filter of his room and expose him to the powerful solar radiation. Meanwhile, the gifts brought by the Adherents of the Repeated Meme contain robotic spiders that immediately work at disabling functions on Platform One. The guests include Lady Cassandra, billed as "the last human", though she remains only a face on a large piece of skin that must be continually moisturised, with her brain in a vat below. The Doctor uses his psychic paper to pass as their invitation to the party, and he and Rose find many elite alien beings there.

They have arrived in time for a party celebrating the final destruction of the long-abandoned Earth by the expansion of the Sun. They land on Platform One, a space station in orbit around Earth. The Ninth Doctor takes Rose five billion years into her future. The episode marked the first appearance of Cassandra and the Face of Boe, both of which would appear in the sequel episode New Earth. Studio work was recorded in the Unit Q2 warehouse in Newport from September to November 2004. 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.

The episode also features numerous intricate costumes. Due in part to the numerous SFX shots the episode used up most of the series' SFX budget. "The End of the World" is the first episode of the revival to be set in the future. 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. 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.
