In Doctor Who, what is the title of the 2010 episode that introduces the Pandorica?

The Pandorica Opens is the Doctor Who episode that introduces the Pandorica.

It is the first part of a two-part series finale in the fifth series of the revived Doctor Who. The episode was written by showrunner Steven Moffat and directed by Toby Haynes. Matt Smith plays the Eleventh Doctor, with Karen Gillan as Amy Pond and Arthur Darvill as Rory Williams.

In the story, the Pandorica is presented as a legendary prison containing an unspecified and supposedly terrifying prisoner. The Doctor and his companions investigate clues connected with ancient civilizations and a mysterious alliance of enemies. The episode ends with a major cliffhanger that continues in “The Big Bang.”

The title echoes Pandora’s box without simply retelling the Greek myth. The Pandorica is a science-fiction device whose mystery and reputation drive the plot. It is therefore distinct from the later episode title and from the mythological container itself.
