After a whirlwind week, the 32-year-old star of Changeling and Kung Fu Panda, which both premiered at the film festival, is back at Paul Allen's seaside villa with Brad Pitt, 44, and their growing brood. The couple is laying low to enjoy family time, and were spotted doing some shopping in Nice.
Jolie and director Clint Eastwood, 77, won glowing reviews for Changeling, which got standing ovations Tuesday and predictions of major awards for both the direction and what Variety called Jolie's "top-notch" performance.
Reviewer Todd McCarthy wrote, "Impressive as she may have been as the wife of Danny Pearl, her performance here hits home more directly."
The Los Angeles Times agreed. "Based on this powerful and searing performance, it would be a good bet she will again be in the hunt for the Best Actress nomination that eluded her for A Mighty Heart last year," reviewer Pete Hammond wrote.
The newspaper also called Eastwood's direction "flawless" and the response to the movie "rapturous."
PEOPLE caught up with Eastwood after the world premiere screening of You Must Remember This,, a documentary on the Golden Age of Warner Bros., which he narrates.
"Angelina is fantastic in Changeling. She is an amazing actress," he said, and when asked about the Oscar buzz added, "I don't want to think that far ahead."
As for the film's sensitive subject matter of a missing child, Eastwood said: "It was fun making it, but I am a little nervous for parents going to see it."
Jolie had previously debuted Kung Fu Panda with costar Jack Black, which garnered a different kind of attention.
Early word from festival-goers was that the animated Dreamworks flick is a pleasing, kid-friendly romp, but what really made news was Jolie's bountiful belly – it was confirmed during an early interview that she is carrying twins.
