Fresh from defeating an attempt by a Sontaran to disrupt British history, the Third Doctor (Jon Pertwee) and his newest companion, reporter Sarah Jane Smith (Elisabeth Sladen), return to present-day London and discover that it has been transformed into a ghost town. Dinosaurs are roaming the streets. The Doctor teams up with UNIT to try to figure out who has been monkeying with time but what he doesn’t know is that the trusted Captain Yates (Richard Franklin) is working with the people responsible for the dinosaur invasion.
Invasion of the Dinosaurs was the second serial of the 11th season. Like The Sea Devils, this was another case where I read the novelization long before I got a chance to see the actual serial. Well-written by Malcolm Hulke, the novelization really got me excited to watch Invasion of the Dinosaurs. It did not prepare me for how fake the dinosaurs would look.
It was to be expected, though. Classic Doctor Who was never known for its wonderful special effects. Instead, it was known for rubber monsters, torn costumes, and alien landscapes that were often made out of cardboard. For many of us, that was a part of its charm. The dinosaurs in this serial look like toys that have been unleashed on a still photo of London. I’ve read that the serial was criticized for its bad dinosaur effects when it originally aired 1974 and that was long before Jurassic Park made everyone take the idea of seeing a realistic dinosaur for granted.
Despite the very fake dinosaurs, Invasion of the Dinosaurs still has one of the better scripts of the Pertwee era. The villains aren’t the typical evildoers who usually showed up on Doctor Who. Instead, they are people who have convinced themselves that the only way to save humanity is to dial back time to what they consider to be the “Golden Age,” before technology and industry blighted what they believe to be the ideal landscape. Of course, they plan to take only the very best among the population to their golden age with them. The villains are elitist environmentalists, convinced that they and only they know what is best. This may be the first episode of Doctor Who where the main antagonist, Sir Charles Grover (Noel Johnson), is a member of Parliament.
Captain Yates’s betrayal of UNIT and the Doctor adds some emotional depth to this story. While Yates was never as important a character as the Brigadier or Sgt. Benton, he was still present for almost all of the Third Doctor’s adventures and the small scenes where he would flirt with Jo Grant were some of the most awkward moments of the Pertwee era. Captain Yates was a loyal member of the Third Doctor’s entourage and his betrayal was motivated not by greed or resentment but instead by a desire to make the world a better place. The novelization made it clear that it was actually the terrible things that Yates saw as a member of UNIT that convinced him that time needed to be turned back.
This was the final Jon Pertwee story to be set entirely on Earth and, though Yates and the Brigadier would return for Pertwee’s final serial, it was the last true UNIT story of the Pertwee years. Jon Pertwee had already decided that the 11th season would be his last. The 12 season would feature a new Doctor. And while the BBC considered actors like Graham Crowden, Bernard Cribbins, and Jim Dale for the role, the Fourth Doctor was ultimately be played by Tom Baker, an actor who was working as a construction worker when Invasion of the Dinosaurs first aired.
Doctor Who would never the same.
