I was on holiday when Tiggs updated here but here's the comments I did for her at the time...
Time to comment on Monster of Peladon. I’m glad you have noticed Pertwee’s tiredness as well, he’s in pain from his back but you can tell the enthusiasm is flagging so it was good that he didn’t stay on for the money (if the BBC had done that, which it wouldn’t) and not enjoy the part. This story is playing with the audience as the Doctor is put through more than the usual ‘is he dead?’ scenes particularly at the end of part four and early in part six. His luck will run out soon… Also for the first time ever, the third Doctor loses in a straight fight and gets punched in the face twice! Doubt they’d allow that now. Shame about the obvious doubling of Pertwee who had been so energetic in Curse and doubled far less in that.
Monster is a lesser story to Curse and is a genuine sequel in the sense similar things happen but not as well as before like most films. Peladon is very faithfully recreated but that shouldn’t be a surprise as the temple, throne room and corridor pillars had all been put in storage in early 1972 and dragged back out two years later. This set saving was virtually unique as apart from the TARDIS and a few Dalek consoles in the 60s, sets tended to be built from scratch every time. Alpha Centauri had the same body but a new head and cloak but still acted like a cock.

As well as Ysanne Churchman as the voice, Stuart Fell is still the body. Ysanne will be back in Planet of the Spiders. The Ice Warrior costumes from 1967 appear one more time with Sonny Caldinez wearing Bernard Bresslaw’s costume. That costume is the one now on display in the Experience and is the last surviving one. Aggedor is the same costume and the same unfortunate Nick Hobbs within it who, as I mentioned on Curse, was the pensioner who threw pony tailed Rory onto the ground in ‘Amy’s Choice’.
I do think the Ice Warriors give the story a much needed kick from part 4, I wish they had arrived sooner. How much people believed at the time they were still peaceful from Curse and were actually surprised they were a baddie breakaway faction is unknown but I do wish the Ice Warriors good or bad would return to Who as they are great characters
Trivia – Nina Thomas, the Queen, would appear in the Sweeney with John Hurt a couple of years later. The Doctor returned to Peladon on audio and in the novel Legacy. This and Curse were the only Pertwee’s without location filming, they did go to the Ealing studios though. It had been used in Curse for the cliff face scenes and in the 60s for lots of things, especially if the water tank was needed. Pertwee’s second new outfit of the season, a rather garish green number with very wide lapels, at least it’s better than the one in the previous story. Fortunately and maybe appropriately, in his last story although it’s another new costume, it will be black which echoes his first costume of 5 years earlier. Ralph Watson who was Ettis was Captain Knight in Web of Fear and will be Ben in Tom’s Horror of Fang Rock. Rex Robinson was Dr Tyler in Three Doctors and will be Dr Carter in Hand of Fear. Not a dr here but he dressed like a badger instead.
Brian Hayles did not write for Doctor Who again, having contributed The Celestial Toymaker, The Smugglers, The Ice Warriors, The Seeds of Death, The Curse of Peladon and this. Malcolm Hulke with the Invasion of the Dinosaurs also bowed out this season (after doing Faceless Ones (with David Ellis), The War Games (with Terrance Dicks), Silurians, rewriting Amabassadors of Death, Colony in Space, The Sea Devils and Frontier in Space. Next story is by Robert Sloman (with Barry Letts) and that will be his last story as well after The Daemons, The Time Monster, The Green Death and that.
I’ll end with my favourite moment – Ettis who is now quite potty, replies to the Doctor with “I don’t be-lieeeve yooouuuu!” A brilliantly over the top bit of acting complete with staring eyes. The next mad character with staring eyes to appear will be Tom Baker…
