Despite the Doctor being definitively killed – and prevented from regenerating – right at the start of this 2011 adventure, several episode-specific versions of the character were released as action figures. An Eleventh Doctor with a Stetson hat and white shirt was made available in 2011, as was a bearded Eleventh Doctor wearing a straitjacket, as seen while he was being kept prisoner in Area 51. The Silents, the main monsters of this story, had the unusual quirk of being completely forgotten about whenever someone stopped looking at them. They were released in cream and grey variants, together with open and closed-mouth options; there were also variants released with Lightning Effect Hands – translucent blue accessories that simulated electricity arcing from their palms. The titular astronaut was released in two versions. On one the helmet visor can be lifted to reveal a little girl inside, while the second contains ns the adult River Song.
