Making a Judd Apatow-directed movie is often a family affair, and rarely more so than on "This is 40," where Apatow not only directs his wife Leslie Mann but also his two young daughters, Maude and Iris Apatow. (He's also featured the girls in "Funny People" and "Knocked Up.")
"I have to be nice to them, because there's other people around," he joked during a Friday morning visit to TODAY. "If there wasn't a crew, I'd probably really yell at them and be vicious."
Still, without knowing it, the girls have their revenge.
"They did take advantage of me," he admitted. "I live with basically three ages of the same woman. ... It's not like three different women, it's like all the stages at once coming at me. I've lost all masculinity at this point."
"This Is 40," starring most of the Apatow clan, opens in theaters on Dec. 21.
