The BBC broadcast Doctor Who’s episode “The Pandorica Opens” in 2010. It is the twelfth episode of the program’s fifth series in its modern revival and was written by Steven Moffat.
The episode builds toward the series finale by bringing the Doctor and his companions to Stonehenge, where the Pandorica is located. The Pandorica is presented as a mysterious prison associated with an unprecedented threat rather than as the simple jar or box of Greek mythology.
Matt Smith played the Eleventh Doctor in the episode. The story also features Amy Pond, Rory Williams, and River Song, while drawing together mysteries developed across the series.
The title is an intentional allusion to Pandora’s box. However, Doctor Who changes the idea substantially: the Pandorica is a constructed sci-fi object with a specific role in the plot. It should not be confused with “The Big Bang,” the following episode in the two-part finale.
