Eventually, Renée says she and Jerry started going off-script and improvised a scene where her character tries to give Barry some coffee. "We're facing each other at the mics, and I see this look come over his face and I just knew that this is when he was going to serve the ace ... and I was going to have to be ready to hit back," she says.
Jerry also improvised his scenes with Chris Rock. "I said, 'Why don't you come in tomorrow? I'm recording. Let's fool around. We'll make up a character for you.' So he came in and we just ad-libbed most of his stuff," Jerry says. "I just interviewed him as a mosquito—so, what's it like out there as a mosquito? And he started saying all this stuff, and we put it in the movie. That was the fun of performing with the people."
