Doctor Who: The Mind of Evil: Episode One ('Episode One' is how it's referred to on screen during the opening credits & not 'Part 1') starts as the Doctor (Jon Pertwee) & his assistant Jo Grant (Katy Manning) arrive at Stangmoor Prison as the Doctor is curious to see a demonstration of a device called the Keller machine which is able to remove & store all anti-social & violent impulses & emotions from a human brain. The Doctor is concerned & sceptical about the process, his suspicions & fears are confirmed when two mysterious deaths occur near the machine. Meanwhile Brigadier Lethbridge Stewart (Nicholas Courtney) & UNIT have their hands full as they provide security for a World Peace Conference taking place in London & it's not long before a Chinese delegate turns up dead. Back at Stangmoor & the Doctor tries to deactivate the Keller machine but it turns itself on & tries to kill the Doctor...

Episode 5 from season 8 this Doctor Who adventure originally aired here in the UK during January 1971 & was the second story from Jon Pertwee's second season as the Doctor & is the only Pertwee story only to exist in black and white although at some point in the future (the eventual DVD release?) it wouldn't surprise me if it was colourised. This six part story was directed by Timothy Combe & this opening episode is really just setting things up & in itself fairly forgettable although still watchable. Apparently originally called 'The Pandora Machine' the script by Don Houghton doesn't really feel like Doctor Who at the moment with virtually no sci-fi elements & no monsters while the whole plot about reconditioning criminals was based on A Clockwork Orange (1971) & the Peace Conference sub plot was added to stretch the story out over it's allotted six episodes. The Mind of Evil moves along at a nice enough pace, the set-up is intriguing & different from the usual Doctor Who story although whether this continues for the rest of it's duration remains to to seen. Overall I liked it & thought it was worth the 25 minutes it takes to watch it but ultimately when all said & done it's nothing particularly special.

This episode has no monsters, aliens or special effects in it so I can honestly say The Mind of Evil: Episode One hasn't a single bad special effect in it which makes a nice change. The locations are nice enough as are the studios although the hand rails on the stair in the prison wobble as people walk up them! The Keller machine itself is a rather clunky looking thing with a horribly dated looking computer the size of a small shed controlling it.

The Mind of Evil: Episode One is a good start & I enjoyed it but I felt some of it was padded & there's still five episodes left! Nothing special on it's own but worth watching & one has to bear in mind it's part of a larger story.
