As for how he and Stone prepared for their quirky scenes together in the movie, Ruffalo tells PEOPLE, “It started with about three weeks of rehearsal, which was just playing theater games, really, and goofing off and cutting up. [That] gave us the feeling of safety with each other and a feeling of fun.”
“It was really daring to be able to be daring and safe with each other no matter how crazy s— got," he says. “And we had Yorgos [Lanthimos, the director] with us the whole time and then we had this incredible script that really lays it all out in the most fun way.”
