Charlotte Rampling - Interview for The Damned 1969 (La caduta degli dei) 

Could it be because she's very well spoken... people were much different it surprised me how young she was in Bobbie wygant interview

Yes it was a french classical music programm held by the lady , Eve Ruggieri. This one edition in tribute of Visconti or "the damned". It was broadcast at the beginning of the 90's, 91 or 92 maybe . I remember Ingrid thulin and Helmut Berger were also invited and a host of other Viscontian actors. I don't remember what was the occasion. Maybe a celebration of Music in Visconti's films. All the actors were dressed up to the nines and it was shot at the opera of Paris, Palais Garnier as I seem to remember. Charlotte would be something like 45/46. It wasn't the best moment in her career. She'd enter a temporary lull that would last pretty much the whole 90's until her great comeback in "under the sand" in 2001.
