In Doctor Who, which 2010 episode title mentions Pandora’s box?

The Doctor Who episode title that mentions Pandora’s box is “The Pandorica Opens.” It is the twelfth and penultimate episode of the programme’s fifth series, broadcast in 2010.

Written by Steven Moffat and directed by Toby Haynes, the episode follows the Eleventh Doctor, Amy Pond, Rory Williams, and River Song as they investigate the mysterious Pandorica. The name is an allusion to Pandora’s box, but Doctor Who reshapes the idea into a legendary prison containing an unknown threat.

“The Pandorica Opens” is paired narratively with “The Big Bang,” the series-five finale. The title is sometimes confused with “The Big Bang” because the two episodes form a continuous story. The episode’s title does not identify the object as a literal box from Greek mythology; it is a science-fiction invention that borrows the myth’s sense of dangerous mystery.
