Unlike a lot of couples, Apatow and Mann do bring their work home with them and believe it strengthens their relationship. Apatow cast their two daughters, Iris and Maude, in his movie, which he describes as an "intimate dynamic." Mann says, "They've grown up watching us do it, so they get it."
"A lot of times it's a dining scene filmed with three cameras, which they don't seem to notice. They get into huge fights with each other and shut down production," she says.
Because of the nature of Apatow's R-rated films, neither their daughters nor their friends are allowed to see any of the movies once they're done.
Some of Apatow's movies have been criticized for their portrayal of the female stars, most notably by "Knocked Up's" Katherine Heigl, who said, "It paints the women as shrews, as humorless and uptight, and it paints the men as lovable, goofy, fun-loving guys."
Mann defends the criticism, pointing out that many of Apatow's female characters are based on her own interaction with Apatow. For example, when Heigl kicks Rogen out of the car in "Knocked Up" because of their fight on the way to the gynecologist, it was based on a real incident in Mann and Apatow's marriage.
"We had a fight going to the gyno's office when I was pregnant for the first time," Mann says. "I kicked him out the car. He deserved it. It was fun to see it on-screen."
Apatow and Mann are also getting better at fighting. "I used to hold grudges," Mann says. "Now, I let them go because I have a bad memory.
"I have such a good time with Judd. He's so great -- such a great director. I get to have input and go into the editing room," she says, quickly adding that the other stars do as well. "My kids are comfortable coming to visit. It's the perfect situation."
