Goodbye Gemini (1970) - Trailer

Goodbye Gemini (also released as Twinsanity) is a 1970 British horror-thriller film starring Judy Geeson, Michael Redgrave, and Martin Potter. Directed by Alan Gibson, it was based on the novel Ask Agamemnon by Jenni Hall. The film concerns a pair of unusually close fraternal twins, Jacki and Julian, discovering Swinging London while home on Spring Break. Their experiences complicate the pair's relationship, which is already strained due to Julian's incestuous fascination with his sister, which he sees as a natural manifestation of what he believes to be the pair's hive-minded nature. The film was produced at a time when conservative groups were beginning to react to the perceived social excesses of 1960s British culture. Coincidentally, it was released concurrently with Freddie Francis' Mumsy, Nanny, Sonny and Girly, another horror film which also dealt with an unusual familial relationship and contained a scene implying consensual brother-sister incest. Gemini and Girly were targeted by the conservative press as endemic of everything wrong with contemporary British culture, resulting in protests and theaters refusing to show the films. The two pictures were ultimately banned in the UK, with Gemini being listed as a video nasty.
