10 Times Doctor Who Gave Fans EXACTLY What They Wanted
8. Classic Doctors Unite!
Any TV show episode in which heroes past and present combine forces is going to be a fan-favourite, and Doctor Who has been doing this for longer than most.
The internet may not've been around during the classic years, but that doesn't mean there weren't hordes of fans excitedly discussing the possibility of seeing multiple Doctors in the same story. It's been apparent since day one that the show's timey-wimey premise would allow for this, and indeed, a multi-Doctor adventure was an idea that was often mentioned behind-the-scenes - well before it actually happened.
Producer Barry Letts finally delivered the goods in 1972/1973 with The Three Doctors, a serial that received a rapturous response from Whovians at the time, with part four racking up 11.9 million viewers - the highest-rated single episode for both Jon Pertwee and Patrick Troughton.
The Five Doctors and The Two Doctors would follow in 1983 and 1985, respectively, and though none of these classic Doctor team-ups had particularly great stories (The Five Doctors fares the best, despite having the largest cast), multi-Doctor adventures are fan-service at its finest, and it's undeniably delightful to watch the likes of Pertwee's suave gentleman butt heads with Troughton's nutty professor.
