S5 E5: 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.
Starring Iain Glen, Matt Smith
