Juliette Binoche confronts an issue every actress eventually faces in Olivier Assayas’s “Clouds of Sils Maria” – what happens when the casting call you get is for the older woman and no longer the starlet? But a woman can’t play a starlet after a certain age, nor should she want to, Binoche, who reached global stardom in such films as “The English Patient” and “Chocolat” said at a post-screening news conference. Binoche said “I think the more experience you have, the more you focus on the really important questions, you open up, you mature, you become more skilled, more honed.”
