History Trivia / TheFortyYearOldVirgin

* StuntCasting: Carol, the woman in the speed dating montage with her [[BestKnownForTheFanservice breast hanging out of her shirt]], is played by longtime [[Wrestling/WCW WCW]] valet and dancer Kimberly Page.

* CreatorChosenCasting: Creator/CatherineKeener was always the first choice to play Trish Piedmont.

* CreatorChosenCasting: Creator/CatherineKeener was always the first choice to play Trish Piedmont.

* DawsonCasting; 19 year old Creator/KatDennings as 16 year old Marla.
** Inverted with 23 year old Creator/SethRogen as Cal who is implied to be much older.

** All of Andy's exclamations during the waxing scene were improvised by Creator/SteveCarell out of the real pain he was going through. Apatow kept separate lists for profane and non-profane ones, so they could mix and match as they pleased.
** Rudd's and Rogen's reactions weren't scripted either (nor was Malco's quick exit- he was genuinely getting sick to his stomach). The two were supposed to appear sympathetic to Andy, but they couldn't keep straight faces.

* StarMakingRole: For Creator/SteveCarell.

* UnintentionalPeriodPiece: The film is very explicitly a product of the early-to-middle part of the 2000s. The electronics store where the main characters work (the two products we see them pitch are a combination VCR/DVD player and a bulky, pre-LCD big-screen TV), Trish’s business selling other people’s items on Ebay, the extended PT Cruiser driving sequence, the low-rider-jeans-and-sequins-heavy fashion, the pervasive trans- and homophobic jokes… all point blatantly to the turn of the millennium. On the other hand, Andy's fanboy-ish passion for classic nerd properties like Creator/MarvelComics and ''Franchise/StarWars'', his interest in computers and the fact that he rides a bike instead of a car--while intended to show how pathetic and undesirable he is--would hardly be marks against him in TheNewTwenties when such interests are considered perfectly normal for adults.

** At one point, Andy complains that he nearly lost a nipple when he got his chest waxed. This isn't just a funny line someone randomly came up with- Creator/SteveCarell is referencing what ''actually happened to him'' while filming that scene. See EnforcedMethodActing below.

** At one point, Andy complains that he nearly lost a nipple when he got his chest waxed. This isn't just a funny line someone randomly came up with- Creator/SteveCarell really DID almost have his nipple ripped off while filming that scene. See EnforcedMethodActing below.

** At one point, Andy complains that he nearly lost a nipple when he got his chest waxed. Creator/SteveCarell actually DID almost have his nipple ripped off while filming that scene- see EnforcedMethodActing below.

* DevelopmentGag: Cal's comments about Andy looking like a serial killer are a reference to reactions from Universal executives to early test footage of Andy riding a bike, believing he looked too much like a serial killer.

** Rudd and Rogen's reaction weren't scripted either. The two were supposed to appear sympathetic to Andy, but they couldn't keep a straight face. Malco's quick exit was also unscripted, as he was genuinely getting sick to his stomach.

* WhatCouldHaveBeen: Creator/Judd Apatow had a part written for Creator/JasonSegel, with the character named [[TheDanza Jason]], but Apatow could not get the studio to approve his casting. Apatow advised Segel because of his unique brand of humor, to consider writing material for himself. Thus Segel wrote ''Film/ForgettingSarahMarshall'', which Apatow served as one of the producers.

** The film is based on a sketch Creator/SteveCarell created while performing with Second City. Carell did many versions of the sketch, trying out different scenarios where the 40-year-old man is hiding a "big secret.

** Rudd and Rogen's reaction weren't scripted ask well. The two were supposed to appear sympathetic to Andy, but they couldn't keep a straight face. Malco's quick exit was also unscripted, as he was genuinely getting sick to his stomach.

* BilingualBonus: The "Guatemalan love song" that Jane Lynch sings had Spanish-speaking audiences laughing. It's not a love song.
-->"When I clean my room/I can't find anything/Where are you going in such a hurry/To the soccer game."
* BreakthroughHit: The film turned Judd Apatow from a working comedy writer to one of the most respected and prolific (and [[FollowTheLeader widely imitated]]) writer/director/producers in all of mainstream comedy.

* DyeingForYourArt: The chest-waxing scene? Yeah, one hundred percent real. ''Ouch.'' For the obvious reason, this was a one-take scene. In fact, at one point they almost ripped off Creator/SteveCarell's ''nipple'', because the actress playing the waxer didn't know she was supposed to apply Vaseline to the nipple and was about to rip off the strip when Creator/JuddApatow realized what was happening and yelled cut. You can also see his blood starting to bubble out, as noted in the commentary. Moreover, Carell's chest had to be kept in its partially hairless state for the remainder of the shoot. The constant maintenance required for this left the actor with ingrown hairs and a nasty infection (according to Carell, his chest looked so bad at one point that his wife couldn't stomach it and made him wear a t-shirt at all times).
* EnforcedMethodActing: See above.

* RealLifeRelative: Creator/SteveCarell's wife Nancy Walls plays the teen clinic sex counsellor. Creator/LeslieMann, who plays Nicky, is married to Creator/JuddApatow.

* WhatCouldHaveBeen: The Smart Tech store manager was originally male.

* IronyAsSheIsCast: The entire film is about a, well, [[ExactlyWhatItSaysOnTheTin 40-year-old virgin]]. Said virgin is played by Creator/SteveCarell- who at the time of filming was 43, had been HappilyMarried for nearly a decade ''and'' had recently become a father of two (the irony was definitely not lost on Carell, who joked about it in interviews).
