In Doctor Who, which 2010 episode features the Pandorica?

In Doctor Who, “The Pandorica Opens” is the 2010 episode that features the Pandorica.

It is the first part of the fifth series finale and was written by showrunner Steven Moffat. The episode follows the Eleventh Doctor, Amy Pond, Rory Williams, and River Song as they investigate the mysterious Pandorica, a legendary prison connected to a major threat.

The story uses the name “Pandorica” as an allusion to Pandora’s box, but it is not a direct adaptation of the Greek myth. The episode ends on a cliffhanger and continues in “The Big Bang,” which concludes the series. Matt Smith played the Eleventh Doctor in both episodes.
