Trivia

Jump to: Cameo (1)
The actors who play Ben's friends all keep their real names for their characters names.
This film features Seth Rogen's first leading role.
The kids who play the children of Debbie (Leslie Mann) and Pete (Paul Rudd) are actually the real children of Mann and director Judd Apatow, her husband.
Ken Jeong, who is a doctor in real life, makes his film debut in this film, playing a doctor.
Jonah suffers from nosocomephobia, fear of hospitals.
This movie was originally going to be a follow up to The 40-Year-Old Virgin (2005), having Seth Rogen and team to reprise their roles as the Smart Tech team.
Since "knocked up" doesn't mean anything in most languages, the film's translation in Russia is "A little bit pregnant." In Brazil it's "Slightly Pregnant". In Italy it's 'Very Pregnant' ('Molto Incinta').
Bill Hader was originally meant to play one of Ben's group of friends, but it was determined that he "looked too old", so he was recast.
Judd Apatow has stated on the DVD commentary numerous times, that the film is partially based on the birth of his and Leslie Mann's first daughter, Maude. Scenes taken directly from reality include:
  • Ben trying to get their doctor on the phone and cursing out numerous doctors when he can't


  • the cantankerous staff physician who Ben has to take out in the hall to calm


  • the argument on the way to the clinic where Allison throws Ben out of the car and they then heated argue at the clinic when he gets there


  • and the scene where Allison tries to take a bath to calm herself just before going to the hospital


The word 'fuck' and its derivatives are said a total of 120 times throughout the film.
The scene where Ben (Seth Rogen) dances with Allison takes place at a Club in Los Angeles called Plan B. Ironically (given this movie's unwanted pregnancy plot), "Plan B" is a brand name for the progestin-only emergency contraception Levonorgestrel.
The maple leaf tattoo on Jay Baruchel's chest is real. He had it done when filming in L.A. on a previous project, where he was feeling very homesick for his native Montreal.
Anne Hathaway was originally cast as Alison Scott but left due to 'creative differences'. In an interview, she revealed that she objected to Judd Apatow's plan to use footage of a real birth. Juliette Lewis, Drew Barrymore, Rachael Leigh Cook, Cameron Diaz, Claire Danes, Tiffani Thiessen, Josie Davis, Uma Thurman and Renée Zellweger all dropped out or were booted out. Christina Aguilera turned it down in order to focus on her music career. Brooke Shields, Jennifer Connelly, Michelle Pfeiffer and Sarah Jessica Parker were deemed too old.
According to the DVD commentary, Jay Baruchel made a deal with director Judd Apatow that he would be the naked guy in the earthquake scene if he didn't have to ride the rollercoaster, because of his fear. Apatow of course broke this by making Baruchel ride, so the part of the naked guy went to Jason Segel.
Judd Apatow was originally planning on using real footage of a woman giving birth for the delivery scene. However, at the last minute, he was unable to because he needed a worker's permit for the yet-to-be-born child.
Much of the dialogue was improvised by the actors or fed to them in the moment by Judd Apatow just before a take.
Ken Jeong, who plays Dr. Kuni, is an actual M.D. He developed his comedy routine while completing his residency in internal medicine in New Orleans.
Jodi, the character played by Charlyne Yi, is supposed to be stoned in every scene she's in. However, in 2009 Yi told The Tonight Show with Conan O'Brien (2009) host Conan O'Brien that she had never gotten high before or after playing the role and in fact didn't even know that the character was supposed to be a stoner at the start of her audition.
Jay Baruchel is terrified of roller-coasters. In the opening sequence where they are at the amusement park he was forced to go on it by Judd Apatow. He only agreed to ride it once, whereas the rest of the cast rode the coaster 7 more times to get all the right takes.
In one scene, Ben (Seth Rogen) mentions that he likes Munich (2005) because 'Jews kick ass'. This was not in the script but was improvised by Rogen on the spot. However, the final film uses only one-third of the complete improvisation (not included in DVD special features). After the film was released, Steven Spielberg phoned director Judd Apatow to compliment the movie and Apatow sent him the complete uncut improvisation of the scene. Rogen would later costar with Munich's Eric Bana in Apatow's Funny People (2009).
The crew members in the studio scenes at E! are actual members of the E! News (1991) crew. However, the editing bay where Alison edits her pieces with Brent isn't an edit bay. It is the studio control room for E! News and the Daily 10.
Paul Rudd contributed much to the discussions and arguments between Pete and Debbie in the film, based on real-life interactions with his wife. The character was loosely autobiographical for Judd Apatow to begin with.
The release name for this film in Portugal translates into "Bloody Bad Luck".
Katherine Heigl said (in 2009) that she considers the movie to be sexist.
Although the role of Ben Stone was always meant for Seth Rogen, Judd Apatow created a mockumentary for the DVD entitled "Finding Ben Stone." The fake documentary chronicles the fictional hard time that Apatow had in finding the right male lead for his film. Among those featured in Finding Ben Stone are Michael Cera, James Franco, and even Orlando Bloom. Although the documentary is clearly satirical, many have taken it to be true.
David Krumholtz, who reportedly is a very good friend of Seth Rogen, was supposed to play a character named "Gummy" but backed out because he was offered the lead role in a Woody Allen film. However, the Allen film fell through and he didn't get the part for "Gummy" back. There's an interview with him and the director on the DVD special features talking about this.
Kim Basinger, Debra Winger and Frances Fisher were each offered the role of Alison's mom, but both turned down the part.
Kristen Wiig's part was originally written for a man until Judd Apatow thought it would be funnier to turn the part into a woman who hates other women.

The montage scenes where we see Seth Rogen and his friends ride a rollercoaster proved difficult. Multiple takes meant that Rogen vomited frequently while Jay Baruchel has a pathological fear of rollercoasters and took a lot of persuasion to go on one in the first place.

Charlyne Yi originally had just one line in the script but Judd Apatow loved her improvisations so much that he just let her riff and generate her own lines.
