[Card] Studio Invasion [Exp.] Reject RD1 [Type] PQ PQ Ref Ref [In-joke] 
The picture is strictly behind-the-scenes material, with Cybermen actors walking into the studio. So is the quote, being from a documentary on “Earthshock”. Invasion (duh!): Speaks for itself. The game text plays on the idea that “Earthshock” had a closed set to keep people from knowing the Cybermen were going to be in it. Note also the BBC Strike, not a card, but a frequent occurrence that has affected Doctor Who’s shooting schedule over the years. References to a BBC Executive, a Producer with “God” (shades of JNT?) and the point about turning off the lights (union rules had the plug being pulled at 10 PM no matter what in the studio).
