This Is 40

This Is 40 is a 2012 American romantic comedy-drama film written and directed by Judd Apatow and starring Paul Rudd and Leslie Mann. A "sort-of sequel" to Apatow's film Knocked Up (2007), its plot centers on married couple Pete and Debbie, whose stressful relationship is compounded by each turning 40.

Filming was conducted in mid-2011, and This Is 40 was released in the United States on December 21, 2012. It received mixed reviews from critics, who praised its cast, acting, and the film's comedic moments and perceptive scenes, but criticized its overlong running time and occasional aimlessness. In March 2022, it was announced that Apatow was in early development of a third film, set 10 years later and titled This Is 50.

Five years after Knocked Up, Debbie owns a boutique, and among her employees are a frumpy cynic and poor saleswoman named Jodi and an attractive and talented saleswoman named Desi about whom Debbie and Jodi gossip, mostly in terms of Jodi hating that Desi exists at all. Pete owns his own record label, but it struggles financially as he promotes the reunion of Graham Parker & The Rumour.

Debbie and Pete also deal with conflict between their daughters, 13-year-old Sadie and eight-year-old Charlotte. For Debbie's 40th birthday, the couple goes on a romantic weekend to a resort. There they get high on marijuana cookies and fantasize out loud about ways they would kill each other.

After speaking with her friends Jason and Barb, Debbie decides to improve her marriage and family through exercise and strengthening her relationship with her father. She tells Pete he needs to stop lending his father Larry money because it is hurting them financially, but he fails to follow through with this.

Meanwhile, Debbie learns she is pregnant but decides not to tell Pete. Later, she yells at a student, Joseph, who had an online argument with Sadie on Facebook leading to a confrontation between Pete and Joseph's mother, Catherine.

Debbie takes Desi out dancing at a club, where she plans to confront her about $12,000 in missing store funds that Jodi has told her were stolen by Desi. They meet several players from the Philadelphia Flyers hockey team there. Debbie awkwardly finds out that one of the players wants to hang out with her and possibly sleep with her. Though flattered, she reveals that she is married, has two children, and is pregnant. He responds with politeness and they part on good terms.

Pete and Debbie deal with Sadie and Charlotte's constant fighting, which puts an additional strain upon the family. They meet with the school principal, but the couple denies Catherine's accusations, and when she starts using the same foul language they had used previously, the principal dismisses them. When Debbie confronts Desi about the missing funds, Desi reveals that she works as an escort and is able to afford nice things because of it. Jodi confesses to stealing the $12,000 to support her OxyContin addiction, and Debbie fires her.
