“This is 40” has debuted two character featurettes, Digital Spy reported.

The videos spotlight Paul Rudd's Pete and Leslie Mann's Debbie.

Starring the characters from 2007's Knocked Up, the film explores the continuing strain placed on the pair's marriage.

Pete's video centres around a magic mushroom-fueled trip to Las Vegas.

The Judd Apatow-helmed movie also features Megan Fox, John Lithgow, Iris Apatow, Maude Apatow, Melissa McCarthy, Robert Smigel, Charlyne Yi and Albert Brooks.

This is 40 will debut in US cinemas on December 14 and in the UK on February 14.
