In the film, Carry on Loving (1970) Sid James and Hattie Jacques can be seen in front of a computer from UFO.
Sid James is no stranger to UFO props. In the one off ITV special from 1969, 'All This And Christmas Too', Sid wears one of the spacesuits.
Other film appearances of Century 21 props included the 1971 James Bond film, 'Diamonds are Forever', and the 1975 sex comedy, 'Confessions of a Pop Performer'.
Woodsy has previously mentioned Doctor Who and the Ark in Space story as one example where the BBC had used some of these props. In fact Century 21 props make quite a few appearances in Doctor Who, not to mention other BBC dramas and comedies, like Doom Watch, Blake's Seven and Moonbase 3, as well as an episode of the 70's comedy, Some Mothers Do 'Ave 'Em, and The Goodies episode, 'Invasion of the Moon Creatures'..
Here we see a scene from the Doctor Who story, 'The Mutants'. In the bottom right hand corner we can clearly see Keith Ford's console from Shado HQ.
In the Green Death, the centre console from Shado Moonbase dominates this set. (As a point of interest Jon Pertwee, as the Doctor is talking with the late Jerome Willis, who played Captain Podley in Gerry Anderson's Space Precinct)
Tom Baker's Doctor aboard the Movellan spacecraft using the curved panels from Shado Moonbase in 'Destiny of The Daleks'.
The BBC also bought models that had been used in some of Gerry Anderson's later series, although in most cases they were heavily altered by model makers like the late Ian Scoones who had previously worked for Century 21 and had joined the BBC, building most of the models for the Pertwee/Baker Doctor Who era, before moving on to Blake's Seven.
This model from 'Frontier In Space', looks like its rear is the capsule from Joe 90's , Most Special Astronaut'.
Another scene from' Frontier In Space'. The Space Freighter on the right is actually made from the Moon Shuttle from UFO.
In this closer view the raised blister sections can just be seen amongst the alterations.
This model from ' Colony In Space' has had very little alteration.
It had previously appeared in the Joe 90 episode 'Talkdown' as the F116, as well as on the front cover of TV21.
There were several more Century 21 prop appearances in Doctor Who and well as Blake's Seven, culminating with the 1985 Doctor Who adventure, 'Revelation of The Daleks'.
Of course there'll be lots of other places I haven't mentioned where Century 21 props can be seen, but one film where I wouldn't have expected to see the futuristic services of Century 21 is 'Up Pompeii',(1971) starring Frankie Howerd, - Titter ye not!
