All Eleven Doctors

Production
Steven Moffat wrote this episode when the BBC suggested doing a special with all the Doctors, instead of The Day Of The Doctor.

Matt Smith's and Jenna Coleman's contracts required them to appear, while Freema Agyeman suggested she played Martha. David Tennant also agreed to return. Peter Davison, Colin Baker and Slyvester McCoy also joined the project.

Christopher Eccleston declined the offer, while Billie Piper and John Barroman were desprate to return. Terrance Dicks (Co-writer with Steven, Mark Gatiss and Neil Cross) suggested the Ninth Doctor was stuck, playing his own timeline on a loop, while Rose and Jack escaped. After a while, John had to decline, due to other commitments. Noel Clarke replaced him.

Tom Baker and Paul McGann were unsure about whether they wanted to reprise their roles. Paul McGann was unsure, because he wanted to be with a companion and if an audio companion came, some fans wouldn't understand. Daphne Ashbrook was found. Tom Baker was unsure because he thought a story with eleven Doctors wouldn't work. Mark promised him that he and Matt would be the main Doctors. Sadie Miller played Sarah Jane alongside him.

Now that Doctors and companions were sorted, the next thing was which villian. Neil pionted out that the Daleks would have to be there somewhere. Terrance added that maybe some 1970s Daleks would be nice, with some Ogrons. John Simm pleaded Steven to be in it and a concept was introduced that there would be Daleks, Ogrons, Cybermen, Weeping Angels, Silents, four Masters (John Simm, Geoffrey Beevers, Eric Roberts and a new Master), Yeti, Ice Warriors, Zygons, Sillurains, and every monster they could find.
