CANNES, France (AP) — Playing an assistant to a famous actress, Kristen Stewart gave the Cannes Film Festival a self-referential and immediately acclaimed performance on the festival’s final day.

Olivier Assayas’ “Clouds of Sils Maria” premiered Friday at Cannes, revealing a new dimension of Stewart, acting in a European production alongside Juliette Binoche. As the cell-phone-tethered assistant to an international, revered veteran actress named Maria Enders (played by Binoche), Stewart’s character is full of ironies.
