It is not often that I say this, but skip this one. Seriously, don't bother. You gain nothing by watching it and don't miss out on anything by skipping it.
I've made no secret of that fact that I am no fan of the work of writers Dave Martin and Bob Barker. 'The Sontaran Experiment' is no exception. It is not that I think it is an absolutely terrible story. It isn't. It isn't even the worst story of this season. It's just an utterly pointless one. Disposable is the best way to describe this story. A forgettable bit of filler sandwiched between two stone cold classics. Honestly, even thought every story in this story is linked, each leading directly into the next, you can easily go straight from 'The Ark in Space' to 'Genesis of the Daleks' and bypass this story altogether.
While the regular cast do their best with the material they're given, the guest actors playing the GalSec astronauts aren't that good. In fact, they are all pretty terrible. I understand that the writers wanted them to have South African accents to show that in the future not everyone would be English (and yet still white). A nice idea. Shame the casting department couldn't find any decent South African actors for them to use.
Notes and Quotes
--Sarah mistakes Styre for Linx ('The Time Warrior'), saying they are identical. I think Sarah needs to get her eyes checked.
--This story was shot entirely on location at Hound Tor on Dartmoor.
--The GalSec crew describe Nerva as 'the lost colony'. It's been orbiting around Earth for thousands of years, you muppets. It's not lost, you're clearly just not looking hard enough.
--One of the GalSec astronauts is played by Glyn Jones, who wrote the season two story 'The Space Museum'.
--Because Tom Baker broke his collar bone making of this story, stuntman Terry Walsh donned a Tom wig and doubled for him in scenes where the Doctor is required to move or engage in physical action.
Harry: "Doctor! I thought you were dead."
The Doctor: "Not me. Piece of the synestic locking mechanism from Nerva's rocket - popped it in my pocket."
The Doctor: "Foresight. You never know when these bits and pieces will come in handy. Never throw anything away, Harry (throws it away). Now, where's my five hundred year diary. I remember jotting some notes on the Sontarans. It's a mistake to clutter one's pockets, Harry."
Vural: "Clock expert?"
The Doctor: "Horologist, actually, and chronometrist. I just love clocks: atomic clocks, quartz clocks, grandfather clocks."
Erak: "He's still lying."
Vural: "Shut up, Erak!"
The Doctor: "Cuckoo clocks."
Sarah Jane: "What you're trying to say is that you're busy and you'd like us to push off."
The Doctor: "I'd phrase it more elegantly myself, of course, but yes."
One and a quarter out of four something, something.
