Zeta One

Zeta One is based on a short story that first appeared in ZETA Magazine.

'Angvia' is an anagram of 'vagina'.

Central character James Word is believed to be named in reference to James Bond, the film series of which was at the height of its success in 1969, and the phrase "my word is my bond".

Filmed at the start of 1969 and run through various edits and reshoots, Zeta One was eventually certified by the British Board of Film Censors at the start of in 1970 and not released widely until early 1971.

The film was shot over a five-week period in January and February 1969, with a budget of only £60,000.

Zeta One was so named as it was intended to be just the first in a series of spin-offs from ZETA Magazine's stories.

Charles Hawtrey's role was initially offered to Frankie Howerd.

Imogen Hassall was initially cast as one of the Angvians but withdrew from the project shortly before filming began.

Scenes in which James Word explains the caper to, unknowingly, one of the Angvians in his flat, were added after production had completed, in order to pad the film's length and explain its convoluted plot to audiences.
