Needless to say, Wim Wenders (City of Angels) admitted to having a huge boyhood crush on her and cast her for one of his early films (Die Angst des Torwarts vor dem Elfmeter).
Here she played the head of a private-eye agency where she has to pose as secretary as the clients and the thugs would not accept her as a dangerous investigator. She co-wrote most of the stories. The series ran for 13 episodes in three seasons until 1965 and is the total Kai Fischer overdose. With that her market value increased even more in the Krimi movies and she appeared in quick succession in: |
Zimmer 13 (Room 13) |
 |
Wirtshaus von Dartmoor
|
Ungeheuer von London City (Monster of London BEW CCC)

Der Würger vom Tower (Strangler of the Tower E.C. Dietrich)
and more TV-krimis always as either call-girl, head of a strip-club, or seductress. Besides that, she toured with the 1950s pop star Peter Kraus (again) in the comedic musical "Bel Ami" - based on the works of Guy de Montpassant whom she'll meet later again....
1967 sees her top-billing the Ernst von Theumer produced schlock-opus "Maneater of Hydra/Island of the Doomed" where she performed alongside Krimi-actress Elisa Montes. She is eaten up by plants in that. If you wanted to know. Director Mel Welles stated that she was in a tense state due to relationship problems and nearly had a nervous breakdown on the set (thanks Robert for that info!).

In 1968 she starred alongside Heidrun Hankammer (Gorilla of Soho) and real-life assassination plotter Tamara Baroni (just out of prison...) in the E.C. Dietrich smutpiece "Die Nichten der Frau Oberst" (The Colonel's Nieces), which was incredibly successful (a top-10 grossing movie of that year) and started the cycle of sex movies based on "literature" (which made it easier for those teachers and professors of language to go into cinemas and watch the movies "Dear, I'm going out to see a movie by Guy de Monpassant, it's for work, you know?"—"Certainly my darling...."). On the set, she had a big fallout with director/producer Dietrich, who claimed to have her hired specifically for going naked, which she refused.

Dietrich should not have worried. Hankammer and Bertoni made this movie an international success.

After that, she took part in the Holy Grail of lost Gialli "Y-XX: Formel des Bösen" an ultra-sleazy "inspiration" to "Cat o' nine tails" AND "Delirio Caldo" of which no moving sequence seems to have survived (KRIMI! is working on this!) but then concentrated on work for tv where she was regularly cast in krimis, though little else. She began theatrical work and wrote her own Krimis under an alias.

She even recorded an LP in 1970 called "Kai Fidelity" with self-penned songs, some were co-written by Jan Hammer (later of Miami-Vice fame). Always to be in the center of the Munich bohemians, she had been present at the "Domicile" Jazz Club where he had recorded his first LP (Live/Jan Hammer Trio/Malma Maliny) Aug.30th 1968. There seems to be another interesting story beneath all of this: Fischer, herself a german-bohemian refugee and center of the munich-bohemian-bohemians (sic!) might actually have been instrumental to this concert. She was close frieds with Friedrich Gulda's wife, the actress Paola Loew. Hammer had just won Gulda's (a renowned pianist) annual newcomer jazz festival earlier. Besides that, Jan Hammer's bassist George Mraz had already played at the domicile too.
Needless to say, both records are published on the same record label by the same publisher. And the owner of the "Domicile" and the "Domicile" publishing company was Ernst Knauff, who at that time, was Kai's current "partner".
The themes revolve around "fidelity" both in a sexual and a philosophical (Wittgenstein) manner. It was lavishly produced but obviously failed to make any impression. A follow up called "Kai Society", for which she had already written some songs, was not released. Her new boyfriend obviously did not own a record company... (source: HörZu 21/1970)
In 1977, Ingmar Bergman casted her alongside David Carradine as aging prostitute in "The Serpent's Egg". Regularly she returned to the realm of TV-Krimis (Derrick) and exploitation pictures like "Holocaust 2 - The Revenge" from 1980. She stayed politically active in numerouse grass-root movements and was an outspoken protagonist for liberal civil rights.
Until 2002 she had one or more photographic-equipment-stores in Munich, and worked as a phtotographer in arts, from there, the traces vanish, but she is still alive.
She could tell us so much, we surely hope she's doing well! And if anyone of you, dear readers, know of her whereabouts, let us know!
