This Is 40 - Trailer

The trailer for Judd Apatow's new comedy This Is 40 has been released.

The film is essentially a sequel/spin-off to the hugely successful Knocked Up, and focuses on married couple Pete (Paul Rudd) and Debbie (Leslie Mann) a few years after the events of the first film.

Melissa McCarthy and Jason Segel appear in the trailer for This Is 40, which takes a lighthearted look at the ups and down of a middle-aged, married couple.

Megan Fox, Lena Dunham, Chris O'Dowd, John Lithgow and Annie Mumolo also star in the movie, which is Apatow's first directorial effort since 2009's good/bad film, Funny People.

This Is 40 will hit cinemas on December 21.
