Julia Robertsis “so proud” of how well she andGeorge Clooneyacted drunk for a scene in their upcoming movieTicket to Paradise.

Roberts, 54, dishes on the making of her and 61-year-old Clooney’s upcoming romantic comedy on the upcoming episode ofAli Wentworth’sGo Ask Alipodcast, out Thursday.

In an exclusive clip, the actress saysTicket to Paradise’s younger cast members “couldn’t believe their eyes” when she and Clooney busted out their best dance moves for the scene.

“We had so much fun, and I will say this: It was so hot. We were sweating. We were not holding back,” Roberts said of filming the scene, in which her and Clooney’s characters drink and play beer-pong with their daughter (Kaitlyn Dever), her soon-to-be husband (Maxime Bouttier) and their friend (Billie Lourd).

“Basically, [director Ol Parker] was like, ‘Here’s the space, stay in it, this is where I can see you, and just don’t hurt yourselves or anyone around you.’ That was pretty much all that we had to do,” Roberts explained.

“And just the first take, you should’ve seen these kids … they couldn’t believe their eyes,” she added. “They couldn’t believe what they were seeing.”

“We were feeding off each other, making each other laugh — I am so proud of how absolutely drunk we seem in that scene. We were stone-cold sober,” Roberts told Wentworth in the clip. “We were hot and sweaty and my hair was sticking to my neck, all the things that I don’t like, and we look like we are having the best time, because we were just sort of egging each other on and it was hysterical.”

“It was so fun,” she added. “We probably could have done it for hours and hours, but they were like, ‘Okay, stop. We’ve had enough. You need to stop now.’ "

In September, Roberts and Clooney both joked that filming a single kiss scene between their two characters took “like, six months,” in an interview withThe New York Times.

“Yeah. I told my wife, ‘It took 80 takes,’ " Clooney said. “She was like, ‘What the hell?’ "

“It took 79 takes of us laughing and then the one take of us kissing,” Roberts added. Clooney responded, “Well, we had to get it right.”
