Dutch public television aired the complete, uncut movie on February 23, 2008. It was the first time hardcore porn had been shown on Dutch public television. It led to discussion all the way up to parliament.
The Radio Times "Guide to Films 2007" picked this as one of 100 landmark films of all time. Radio Times' film editor Andrew Collins said that the list is about a film's influence on society, not cinematic quality. Collins said "'Deep Throat' is not necessarily recommended for everyone. It's a quite badly made film, but to deny its influence would be pure snobbery."
When the film was released theatrically in the US, many companies were investigated by law enforcement agencies, including the Federal Bureau of Investigation (FBI). A number of them were convicted of distribution of obscenity.
The total box office revenue has often been stated as $600 million. As noted by Roger Ebert in his review of Inside Deep Throat (2005), most of the porn theaters in pre-video days were owned by the mafia. Inflating box office receipts could have been one way to launder money from drugs and prostitution. More conservative estimates put the figure around $100 million. Whatever the case, very few of the people directly involved in making the film saw much of the money. According to Inside Deep Throat (2005), much of the box office disappeared when mobsters came to cinemas to collect the profits.
Harry Reems was the first actor ever to be prosecuted for distributing obscenity. Co-star Linda Lovelace and director Gerard Damiano made a deal with the prosecutors in exchange for immunity, so the court focused all attention on him. Reems received open support from Hollywood stars, including Jack Nicholson and Warren Beatty. The conviction was overturned on appeal one year later.
According to a New York Times article published in January 1973, director Gerard Damiano originally signed a deal that entitled him to one-third of the profits. Damiano claimed he later sold his interest for $25,000, reputedly under pressure from partners involved in organized crime.
The film contains a number of references to the James Bond film series. The James Bond theme song can be briefly heard in the soundtrack. Dr. Young refers to "case 007". At the time, Terence Young had directed most of the James Bond films.
Star Linda Lovelace later distanced herself from the movie. She claimed in her autobiography that Chuck Traynor, her then-husband, coerced her into participating. She said he would often persuade her to engage in sexual acts in front of the camera, and later prostituted her under threat of guns and violence. Several people confirmed that Traynor was controlling and abusive on set; and Traynor himself admitted it.
