"Girls Gone Wild" mogul Joe Francis wrote a letter to producers saying he was angry at the film because of Jerry O'Connell's character who owns a site called "Wild Wild Girls", which is a spoof of the adult video line, and that he might take legal action if "any defamatory or disparaging statements, or depictions, in the media or in the film itself, or other statements that portray Mr. Francis in a false light, will be met with swift litigation." After seeing the movie, Francis went on saying "I appreciate a good parody as much as the next guy, but to associate me with drugs, and the filming of underage girls crosses a definite line", Francis said. "Jerry O'Connell has repeatedly and emphatically stated on the public record that he is 'playing Joe Francis', not a fictional character based on me. Mr. O'Connell has done this, despite having been warned by his own lawyers not to admit this." In response, O'Connell said "I get to play Joe Francis! Oh, wait. For legal reasons I'm supposed to say, 'I play someone loosely based on Joe Francis.'"
Gianna Michaels was a last minute replacement for Natasha Nice, who got arrested while working on a hardcore movie prior to the shooting of her scene, and was unable to do the small part Michaels plays in the picture.
The film was actually shot on Lake Havasu, Arizona, a popular place for real spring breakers, not on Lake Victoria. Producers debated using the real name, but opted for a fictional one for various reasons.
Kelly Brook auditioned with an American accent. This deeply disappointed Alexandre Aja, who called her back and asked her to speak in her natural English accent. He felt the character would be much more appealing if Brook played her in her normal voice.
During the scene of the two nude women swimming underwater, the music used is the "Flower Duet" from Delibes' opera "Lakmé". The English translation of the French lyrics includes the lines "Come, let us drift down together / Let us gently glide along; With its enchanting flow / Let us follow the fleeing current... Ah! Let us drift down together!"
Eli Roth woke up after a full day of shooting his part with his eyes being completely bloodshot, and his vision blurry, and went to a local doctor in a panic. The doctor amusedly asked Roth if he'd been spending a lot of time in the sun, and responded to Roth's confirmation of this that he'd simply gotten an irritation from having sunblock mixed with sweat get into his eyes. Roth switched to a different sunblock and had no problems for the remaining days he was playing his part.
Adam Scott told an interviewer that making the film was like being in Apocalypse Now (1979), not based on the enjoyable experiences of working with the other actors, actresses, or Alexandre Aja, but because it was brutally hot on-set in Lake Havasu City Arizona. Elisabeth Shue responded to being told of Scott's comments with "I'm glad he said that."
In Matt Boyd's (Richard Dreyfuss') fishing scene, not only is he dressed like his Jaws (1975) character Hooper singing "Show Me the Way to Go home", as he did aboard the "Orca", further references to the Jaws film franchise include the brand of the beer he is drinking, "Amity", and in a nod to Chief Brody's famous line regarding needing a "bigger boat", he is set up in an incredibly small 1950's vintage one man fishing boat the size of a bath tub.
