famous for having pubic hair in Blow-Up (though that's nothing to what her daughter's done on screen) but she had more of a role in Death on the Nile. Most of her films were French, so I don't suppose they're widely seen here.
She and Serge Gainsbourg were as big a part of late 60s culture in Paris as John & Yoko or Mick & Bianca were in London. Absolutely iconic in an age when having a "foreign bird" on your arm was the ultimate status symbol...
