Shot back in 2009 on location at Dover Castle, this look at the making of the story is made unexpectedly poignant by the appearance of Nicholas Courtney and Barry Letts, who both passed away in the intervening years. Featuring actors Nicholas Courtney, Pik-Sen Lim and Fernanda Marlowe, director Timothy Combe, producer Barry Letts and script editor Terrance Dicks. Narrated by Cameron McEwan.
