London: Producer-director Judd Apatow has said that his latest film `This is 40` represents the maturity in his filmmaking.
Apatow, who has previously had success with teen comedies like `Superbad`, `Freaks and Geeks` and `Undeclared`, tackles a married couple`s mid-life crisis in his most recent movie, reported Digital Spy online.
"I`m 44 years old. I`ve written about high school, college. But most of my life isn`t about that transition anymore. So it`s a challenge to explore other periods of your life. I still find nothing funnier than that period. That moment when you have to define yourself and grow up is hysterical because we`re all such a mess in that moment," Apatow said.
"That`s why there`ll always be a lot of movies and television about 15- to 25-year-olds `cause it`s when you make the most mistakes," he added.
`This Is 40` stars Apatow`s real-life wife Leslie Mann and their daughters along with friend Paul Rudd.
The film is now playing in the US and opens in the UK on February 14, 2013.
