Juliette Greco, I watched
The Big Gamble 1961 just after she passed away, an African adventure about distributing beer, a movie that doesn't take itself too seriously, not a typical Greco role, but it was rather entertaining.
She had a much better role as a femme fatale in
Maléfices aka
Where the Truth Lies 1962, that takes good use of location shooting on the French coast, with an island that can only be reached in low water, and might have put a spell on a veterinary, a bit slow but a very worthwhile watch in the end.
She had a successful singing career to fall back on, something the others might not have had.

I voted Greco, by the way.
Darvi I don't think I've seen in anything.
Demick, well I've seen
Those Magnificent Men in Their Flying Machines 1965 without remembering she was in it, though it was many years ago, and rather recently
Le clan des Siciliens aka
The Sicilian Clan 1969, but that movie was more about the men (Delon, Gabin, Ventura), even if it turns out to be a vital part, the actual role is rather small.

Though she got to roll around with Delon on the beach in
The Sicilian Clan
Gilles, I've only seen in
Hello-Goodbye 1970 many years ago and it didn't leave much impressions on me, more than it felt like it belonged to another era.
