Wes Anderson and Bill Murray teased a Western project during a surprise onstage reunion in Paris, with Anderson saying he and Murray have “for many years” talked about making one — potentially with Owen and Luke Wilson.

The exchange took place at Cinema Paradiso, the star-studded four-day festival of open-air screenings and live music organized by indie film powerhouse MK2 in the courtyard of the Louvre museum in Paris from July 1-4.

While Anderson was presenting his 2014 classic film “The Grand Budapest Hotel,” Murray popped up on stage and delighted the crowd with his deadpan riff about what the filmmaker is like on set.

“The question is: what is Wes like to work with on set?” Murray said, standing beside Anderson. “As you can see, he has a beautiful smile. Come on, smile. He has a beautiful smile, and he withholds it. He does not give us a smile all through the day.”

Murray continued, “You can do a take, you can look at your director, you can finish the scene, you can shoot the reverse — nothing. But later, after Wes has had dessert, here comes that beautiful smile again. So he really needs dessert all day long.”
