CANNES WATCH: Catherine Deneuve says rise of social media has dimmed stars’ wattage

CANNES, France – French acting icon Catherine Deneuve is a cinema supernova. And she says they don’t make stars like they used to.

Deneuve told reporters in Cannes Wednesday that glamour needs mystery, and that’s hard to achieve now that social media has blurred the boundary between private and public.

Deneuve said the all-revealing nature of celebrity culture doesn’t “let people dream anymore” about celebrities.

“The private lives of actors and actresses are displayed around the globe,” she said. “People even post up their own private photos on these social networks, and I find that a pity.

“That isn’t conducive to dreams.”

Deneuve’s message fits with the mood of a Cannes festival that is trying to eradicate selfies — another symbol of our oversharing age — from the red carpet.

Deneuve made her Cannes debut in 1964 in multicolored musical “The Umbrellas of Cherbourg.” The 71-year-old star plays a family-court judge trying to tame a teenage tearaway in this year’s festival opener, Emmanuelle Bercot’s “Standing Tall.”

The 68th Cannes Film Festival runs to May 24.
