Back in 2007, Knocked Up, a rom-com featuring some of the biggest names in the comedy genre, hit theaters. Written and directed by Judd Apatow, this production follows Alison, an up-and-coming journalist who has just been promoted at work and, as a way of celebrating, goes out clubbing with her sister. At the nightclub they go to, she meets Ben, an immature and lazy man with a totally different life than hers, but with whom she ends up sleeping after drinking way too much. Even though they break off contact the following day, they have to reconnect a couple of weeks later because Alison finds out she is pregnant. After this news, they both try to navigate this strange journey together despite the fact that they have very little in common.

Knocked Up starred Seth Rogen, Katherine Heigl, Paul Rudd, and Leslie Mann, and became a box office hit, grossing $219 million worldwide. Such was its success that, a few years later, Apatow went on to work on a sequel focusing on Rudd and Mann's characters called This is 40. Even though it was successful, Knocked Up had its share of controversy due to the statements made by its leading actors. In an interview with Vanity Fair, Heigl stated that she considered the film to be rather sexist in its portrayal of women, something that did not sit well with Apatow and Rogen. Eventually, however, the stars managed to smooth things over and put their issues behind them. Here is a review of the most recent projects of the cast of Knocked Up.

Katherine Heigl

In Knocked Up, Katherine Heigl is Alison Scott, the famous reporter that gets pregnant following a one-night stand. This actress is probably best known for her role as Dr. Izzie Stevens in Shonda Rhimes' series Grey's Anatomy, a production in which she starred until 2010. After her appearance in the rom-com alongside Seth Rogen, Heigl went on to star in several films of the genre, such as 27 Dresses, The Ugly Truth, and New Year's Eve. In recent years, however, she has not been as active in the industry, but after a few years of not starring in any film, she was cast in the psychological thriller Fear of Rain in 2021. Nonetheless, she was involved in some TV projects, such as the series Suits and Netflix's Firefly Lane, where she also serves as executive producer.
