The 'Doctor Who' Series 7 opening episode features a Dalek first used in 1967.
The Time Lord's most infamous nemesis returns in upcoming adventure 'Asylum of the Daleks' and the production team searched for as many original versions of the metal-encased aliens as they could.
And one extra-special prop they located was a Dalek used 45 years ago in 'The Evil of the Daleks' - which was broadcast in black and white and featured Second Doctor Patrick Troughton.
During a Q&A session at the screening of the episode at the BFI Southbank in London last night (14.08.12) host Richard Bacon asked showrunner Steven Moffat how many of the Daleks in the episode were original props.
Referring to 'Doctor Who' brand manager Edward Russell, Steven replied: "I'm not absolutely sure, maybe Ed knows if he's sitting somewhere?"
Shouting back from the audience, Edward said: "The one from 'The Evil of the Daleks' is real, the rest are replicas from the 60s.
Steven added: "That is a prop from a long time ago."
Steven also revealed the Dalek he borrowed from formed 'Doctor Who' boss Russell T. Davies for the action-packed episode was returned to him slightly "scorched".
The 50-year-old writer revealed: "There's one Dalek from Russell T. Davies' hallway. Before he was 'Doctor Who' showrunner, Russell was just that cool guy who got a Dalek made for himself so he could have it in the hallway and show it to guests. But when people asked him if it was a real Dalek, he would have to say, 'No it's a replica.' So when we were doing this we thought let's ship it from Manchester and canonise it so it's a proper Dalek. So in future he can say, 'Yes it is.' It's been returned to Russell's hallway with slight scorching, I've very pleased to say."
Steven also promised fans the warring mutant race will always come back to the BBC One series, no matter what happens to them on screen.
He added: "The Daleks will always come back to 'Doctor Who', every time we say we've wiped them out it is definitely a lie. They will always return."
Main stars Matt Smith - who plays the titular Time Lord - Karen Gillan and Arthur Darvill took part in the Q&A as well as executive producer Caroline Skinner.
'Asylum of the Daleks' will air on BBC One in September.
