A for Andromeda proved to be just as popular with the viewing public as the final Quatermass serial a few years earlier, with ratings escalating sharply as the story progressed. Needless to say, the strength of the scripts had already prompted work to begin on a follow-up serial before production of A for Andromeda had even begun.
Picking up from the conclusion of the previous story, The Andromeda Breakthrough saw the mysterious Intel organisation (almost a prototype for The Man from U.N.C.L.E.s THRUSH) building a replica of the alien computer in the newly independent, middle-eastern country of Azaran. With Madeleine Dawnay already recruited, and Andromeda and John Fleming spirited away from the UK, the scene was set for for a further battle against alien technology, as the world's weather systems start to become increasingly violent — a direct consequence of one of Dawnay's failed experiments in A for Andromeda.
The sequel saw Susan Hampshire replacing Julie Christie as Andromeda, whose movie commitments clashed with the shooting schedule, meaning that she only performed in a limited number of scenes before leaving the production. Many of the other cast members from the original story also reprised their roles, including Peter Halliday, Mary Morris, John Hollis, and Noel Johnson as Osborne.
As with many programmes of the era, the majority of A for Andromeda was destroyed during the 1960s after its commercial life was considered over. The Andromeda Breakthrough, however, managed to escape unscathed, and still exists in the BBC archives as a set of 35mm telerecordings.
The Italian television network RAI subsequently produced their own adaptation of A for Andromeda in 1972, with the five-part serial being produced in black and white and on videotape just like the UK original. To this day it remains one of the few original UK sci-fi TV productions to be re-made in this manner.
A further production of A for Andromeda occurred in 2006 when BBC Four commissioned a ninety-minute re-make as a follow-up to their 2005 update of The Quatermass Experiment. By a bizarre coincidence, a 16mm print of the sixth episode from the 1961 original was returned to the BBC archives just a few days after the new version was announced.
The majority of A for Andromeda remains missing from the BBC archives but, despite this, 2 Entertain still managed to assemble The Andromeda Anthology in 2006, which collected together all of the existing footage from A for Andromeda and the complete Andromeda Breakthrough. A complete off-air audio recording of The Last Mystery was subsequently returned to the BBC late in 2006.
The Italian production has been released in its country of origin on both DVD and video, but sadly without English subtitles. family
This seven-parter by Fred Hoyle and John Elliot transformed Julie Christie from an unknown drama student into a star. Scientists receive radio signals from the Andromeda galaxy, giving instructions for building a computer. Once on-line, the computer creates a perfect human replica, Andromeda (Christie). The machines design new innovations for the British Government, but the leading scientist John Fleming believes the computer is intent on world domination. Thanks to archive junkings in the 60s, all that survives of A for Andromeda are the titles and a film insert from part 1, and 3 reels of 16mm telerecordings from the final episode. This title sequence featured in Channel Four's 1001 Nights (1991), in a sequence examining wiped dramas.
