A behind-the-scenes clip of the saddest moment from Doctor Who has resurfaced online... and I'm not sure I'll ever be able to look at it the same.
It's been 20 years since the BBC aired the Doctor Who season 2 episode 13 episode 'Doomsday,' in which the Doctor (David Tennant) and his companion Rose Tyler (Billie Piper) share a gutwrenching goodbye on a beach. That, and the scene that comes shortly after (where they're both trapped on other sides of a wall), has always been enough to make me cry just by thinking about it.
