Blinded by the Light

Actress Karen Gillan tells how the 'Crack in Time' series story arc fits into this episode, while writer Steven Moffat describes how the very first crack in time was actually in his son's bedroom wall. As we prepare to say goodbye (for now) to River Song, the cast and crew examine the character's shady story so far and speculate about her possibly even shadier future, while Gillan gives a guided tour to Amy Pond's bedroom. Featuring interviews with Matt Smith, Karen Gillan and Alex Kingston.
