The Big Bang

"The Big Bang" is the thirteenth and final episode of the fifth series of British science fiction television programme Doctor Who, first broadcast on 26 June 2010 on BBC One. It is the second part of the two-part series finale; the first part, "The Pandorica Opens", aired on 19 June. The episode was written by head writer and executive producer Steven Moffat and directed by Toby Haynes.

Following the end of the previous episode, alien time traveller the Doctor (Matt Smith) is trapped in a prison from which escape is impossible, the space-time vessel the TARDIS has blown up with the time-travelling archaeologist River Song (Alex Kingston) inside, and the Doctor's companion Amy Pond (Karen Gillan) has been shot and killed by an Auton replica of her fiancé Rory Williams (Arthur Darvill). As the universe is collapsing, the Doctor uses time travel to solve these problems and ultimately reboot the universe.
