All excellent guesses Mes Dames!
Top pic is Anouk Aimee (A Man and A Woman, 8 1/2, La Dolce Vita). She's 74! I saw the Cannes photos and I thought she was so damn beautiful.
Bottom is Arielle Dombasle at Cannes age 53. She's an actress (cough). Looking a bit pulled up! She's married to Bernard-Henri Levy who wrote American Vertigo.
