玛丽·麦克科马克 originally did not want to accept the role of Alison because of 霍华德·斯特恩's controversial reputation. She accepted the chance to audition only because she wanted to meet director 贝蒂·托马斯. When McCormack told Thomas that she was refusing the role, Thomas encouraged her to listen to Stern's radio show and meet him in person. McCormack became a fan of the show and accepted the role.
According to 霍华德·斯特恩, he at first believed that he would be able to improvise throughout the movie, as he does on his radio show, and did not memorize his lines. Producer 伊万·雷特曼 had to pull him aside and explain to him that he needed to learn his lines as scripted.
约翰·斯塔莫斯 introduces Howard's Fartman character in the opening scene but in real life it was 卢克·贝里. Perry later admitted to Stern that he feared the movie would not be good and turned down the chance to play himself.
The film's opening "Fartman" sequence is based on 霍华德·斯特恩's appearance on the 1992 MTV Video Music Awards. Stern (as Fartman) and 卢克·贝里 (约翰·斯塔莫斯 in the film) presented the award for Best Metal/Hard Rock Video to Metallica for their "Enter Sandman" video; drummer Lars Ulrich and lead guitarist Kirk Hammett accepted the award. Perry and a female audience member managed to each grab a handful of Fartman's posterior, while Ulrich grabbed Fartman's codpiece. The other nominees for Best Metal/Hard Rock Video were "Let's Get Rocked" by Def Leppard, "Everything About You" by Ugly Kid Joe and "Right Now" by Van Halen.
The character of Kenny 'Pig Vomit' Rushton is based on Kevin Metheny, the WNBC radio program director at the time. In real life, Howard called him 'Pig Virus', not 'Pig Vomit'. Pig Vomit was the name of the group that did Howard's opening theme song for his radio show at the time.
In his final monologue, Kenny Rushton states that he is no longer working in radio and works as a manager of a shopping mall. In real life, Kevin Metheny, on whom Kenny is based, worked in radio until his death in 2014.
霍华德·斯特恩 appears on [error] wearing a T-shirt reading "On Strike Against NBC" and openly criticizes the network while 保罗·吉亚玛提 plays an executive who watches this on TV in dismay. Giamatti later starred as Harvey Pekar in 美国荣耀 (2003) which features a scene where Pekar causes a stir when he criticizes NBC on the same show while wearing a T-shirt with the same words written on it (which happened in real life).
On May 23, 2001, 霍华德·斯特恩 said on his radio show that the scene where the Duke Of Rock goofs on him and calls him Big Bird was actually based on an incident with rock vocalist Steve Perry (of the band Journey). Stern recalled, "I walked in and he was on another guy's show . . . and he was like, 'Hey, look at this douchebag'. Remember in my movie the Duke Of Rock is goofing on me? That wasn't based on the Duke Of Rock, that was based on Steve Perry . . . Yeah, he just goofed on me. 'Hey Big Bird, what are you doing?'" In the article "Who Is Howard Stern?" in the June 14, 1990 "Rolling Stone Magazine," it's noted that Stern had described himself as looking like a cross between Big Bird and 乔伊·雷蒙.
The movie showing in the theater where Howard goes to view the premiere with the B-movie actress is called "Die Watching". Actress Melanie Good, who plays the B-movie actress, starred in a movie of that name in 1993 (Die Watching (1993)).
Mary McCormack claimed that one of the reasons why she accepted the role, after initial reluctance because of Howard Stern's controversial reputation, was how it would affect her film career. She confided this to "Murder One" co-star Stanley Tucci over a lunch. Tucci quipped "What film career?" over her objection. McCormack decided to accept the role after Tucci advised her that she should accept it.
For the scenes that featured 霍华德·斯特恩 in high school, filming was done at Union High School in Union, NJ. 阿尔蒂·兰格, who would join "The Howard Stern Show" years later, graduated from the very same school.
In 1999 the USA television network bought the rights to broadcast the film for its network television premiere. Howard Stern was initally hesitant to have the film censored, but because the network was willing to pay such a high price for the film to be shown on television, he relented and allowed the censorship. Since Stern did not want any dialogue dubbed over strong language and did not want any alternate scenes substituted for nudity and sexual content, the film's broadcast was unique as the strong profanity was simply beeped over and the nudity was pixelized. Stern also occasionally paused the film to comment on the censorship in a humorous way. This version of the film was also broadcast on VH1 as part of "Movies that Rock" in 2006.
Despite being in the movie, Robin Quivers was never fired. She was instead temporarlly given time off while Howard attended speech therapy to better his voice and pronouncing his S. Once his show returned, so did Robin.
Howard's rise to being the #1 disc jockey in America celebration never took place in real life. Nor did he ever have AC/DC perform at his request. The event is a depiction of rallies or funerals for DJ's Howard and his crew would put on in any market they became number one in that particular radio market.
