The pair play warring exes who come together to sabotage their daughter’s wedding. They go toe-to-toe in an after-the-credits scene when they sling mean comments at one another. In a recent interview, they revealed that they’d improvised a great deal of the dialogue in that scene.

“Julia would take everything too far. I will tell you,” said Clooney during an interview on Wednesday’s SiriusXM’s The Jess Cagle Show.

“George has no feelings,” Julia retorted.

According to the stars, fellow actors in the scene were not ready for the harsh jokes between the real-life close friends. “The funny thing is you could tell by the background artists who were standing around us when either of us took it too far. ‘Cuz they would react,” Clooney said.

Roberts said costars would audibly gasp when a joke was particularly rough.

“It really was funny because there is the couple of times where I was like, ‘Too much?’,” Clooney added.

The jests were “dangerously close” to reaching the point of no return, but their friendship managed to survive.

“We’re still friends. Don’t worry,” she said. “We made it through.”

The pair have remained only friends despite their chemistry on screen in movies like the 2001 remake of “Ocean’s Eleven.” In the interview, Clooney also addressed why the two never dated in real life.

“Julia was always in a relationship, or I was in a relationship. And we were fast friends right away,” explained Clooney. “It’s been nothing but fun for us. So, I don’t think that was ever really a thing.”
