Mon frère... mon assassin

The freak twins, Judy Geeson (Jacki) and Martin Potter (Julian) come to London to stay in a house in Chelsea and they immediately hit the party scene thanks to a meeting with Alexis Kanner (Clive) in a pub. Kanner is strange – he's a nasty conman who uses people but he's not as strange as the twins. Geeson and Potter are both child-like with Geeson laughing way too much at things that aren't funny and Potter being obsessively possessive about his sister. Worse, they love each other – and I mean actually love in an incestuous way that includes a physical relationship. So, it's uncomfortable viewing. The twins exact revenge on a couple of people. Are they untouchable?

This film is way too weird and not particularly enjoyable. You watch because you don't know where it's going but once watched, I think you get rid. It reminded me a bit of "Beyond the valley of the Dolls" but set amongst a seedy London party scene. Both films are not good and dish out some horror as well as peculiar characters that are scary and hard to relate to. Scary in a sexuality scary kind of way. Michael Redgrave (James) pops up in this as a familiar face on TV whilst Mike Pratt (Rodd) is probably the best in the cast as a debt collector.

As a Londoner, I recognized the locales – I spotted Cheyne Walk, Notting Hill Gate and Shepherds Bush Market and I know for a fact that there were hotels like that in Paddington in the 1980s. Dodgy ones. The central characters of the twins were just too weird.

Infantile psychotic twins Jacki and Julian (Judy Geeson and Martin Potter) arrive in London, immediately arranging an accident for their grouchy landlady so that they can have the run of the place. The siblings then set about experiencing the swinging London party scene, where they meet louche rogue Clive (Alexis Kanner, sporting some impressive mutton-chops). After Clive is roughed up by a bookmaker to whom he owes £400, he tricks Julian into bed with a pair of transvestites, takes a few photos and proceeds to blackmail the young man. However, instead of getting cash for his troubles, Clive gets knifed in the neck instead.

As a child of the '70s, I have an affinity with films from that era, especially those set in the UK, but Goodbye Gemini was a tough one to endure. It's horrible, hippy nonsense that features hedonistic characters hard to sympathise with, atrocious dialogue, and incomprehensible behaviour from all involved. An incestuous relationship between the inseparable twins is hinted at, which adds an edginess to proceedings, the music is groovy, and there are a couple of outrageously camp homosexuals who are mildly amusing (one wears a bright pink shirt and uses the word 'ducky' a lot—you don't get much more '70s than that!), but there really is very little else worthy of mention.

This.seems to be a hangover from the swinging sixties.A very strange story and weird characters.It is difficult to know what Michael Redgrave is doing in this.The film is a total mess and wouldn't have advanced the career of anyone involved with it.

Twins Jacki (Judy Geeson) and Julian (Martin Potter) arrive in swinging London and quickly fall in with the wrong crowd. Well, smarmy Clive (Alexis Kanner) to be more specific. Clive worms his way between the tight bond the twins have and, after he threatens to blackmail Julian, some killing goes down. This is a pretty minor horror-thriller as nothing really happens for the first 50 minutes. After that, it is a half hour of overwrought drama as Jacki runs from the law and gets help from an old guy. The film's biggest merit is probably the capturing the bars, folks and style of late 60s swinging London. Oh, and the hippest debt collector you will ever see. There is also some pretty snappy dialog and Kanner is really good as the would-be blackmailer.

Takes place in 1970 London. Jacki (Judy Geeson) and Julian (Martin Potter) are 20 year old twins who live together and love each other (incest is implied) Then they meet Clive (Alexis Kanner) who breaks up their little fantasy world. This leads to blackmail, murder and a very disturbing ending.

Forgotten thriller/horror movie. The script is good and the acting is great (Geeson and Potter are excellent) but it is dark and disturbing. It's not a blood and guts film (the one murder is obviously faked) but it does work on you. This may be too dark for some people but I found it fascinating. Good luck with the thick British accents.
