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.

"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.'"

Let us drift down together!"
