Behind the scenes
Ilya's full name is given, in Russian, on the prominent name tag on the man's uniform, with surname first and first name last. Though iPlayer credits reportedly list the character as "Ilya", the version of the episode available on iTunes credit Andrew Byron as playing "Llya" instead.
While Ilya is described by the sonic sunglasses as being 70 years of age, the actor, Andrew Byron, was only 45 years old at the time of production.
