Leslie Mann Not Ready for Daughters to Be Stars

Judd Apatow's This Is 40, the self-labeled "sort-of sequel" to the 2007 film Knocked Up, continues with the lives of "Pete" (Paul Rudd) and "Debbie" (Leslie Mann) as well as their two children, portrayed by Apatow and Mann's daughters Maude and Iris. At the Los Angeles premiere for their quasi family film, the Apatows revealed their experience working with each other.

"It's fun because we get to sit at the dinner table and have creative conversations about what we're going to do at work the next day," said Mann, who married the comedy filmmaker in 1997. "We always have a lot to talk about and my kids get to be creative, and it's really fun."

The upcoming comedy will be the Apatow girls' third film, as they were also featured in Apatow's Funny People as Mann's character's children in addition to Knocked Up. While the girls have had the fortune of appearing on the big screen at a young age, their mother doesn't think it's time for them to become full-time movie stars.

"Maybe not right now," Mann replied when asked if she wants her children to become movie stars. "If they want to do it later, that would be O.K. with me but I want them to focus on school right now and their math tests. I like the fact that Maude is writing because then if she does decide to do this for a living, she can create her own work and doesn't have to rely on other people to give her a job."

Apatow--who was happy to have his daughters on his production--wrote, directed, and produced the comedy as he did with the other two films in which his daughters acted. The only other film for which he took on all three capacities was another film centered on 40-year-olds: The 40-Year-Old Virgin.

"I think a lot of people can relate to it," the comedy film mogul said of his latest film. "It's about family and life and a hard, funny week in the life of a family."

While Apatow was on the verge of 40 when making 40-Year-Old Virgin, it is his wife this time around who is 40 in this film, having reached the four-decade mark in March. Mann, who has been in six of her husband's prior films including the film on which they met (The Cable Guy), said the film is spot-on.

"It seems like so many people who have seen the movie have come up to me and said, 'I feel like you have a video camera hidden in my house and you've been taping me' because there's so much in it that is so relatable," she said.
