Originally slated for a PG-13 classification, the film would have had a more adult tone that parodied the original series. Shaggy was gonna be a stoner, Velma and Daphne had a side lesbian relationship, and there were several allusions to marijuana. In 2017, James Gunn stated that the edit almost received a R rating and that they had to utilize CGI to remove the female characters' cleavage. Shortly after the film's completion, Freddie Prinze Jr. (the film's Fred) expressed his dislike for having his hair tinted blonde and ended up cutting it completely off.

[edit] Dialogue
Velma: Jinkies, jinkies! Fred? Enter, Fred. Can you hear me, Fred? Fred: Velms, this is Fredster. Velma: Daphne has been apprehended once again. That is acceptable. When the Luna Ghost and Daphne reach the corner, Shaggy and Scooby will emerge from the barrel— Fred: Furthermore, you will trigger the conveyor belt, dumping the oil tank onto the floor. Velma: Just keep in mind my strategy.
Freddie Prinze Jr. and Sarah Michelle Gellar, who co-starred in I Know What You Did Last Summer and depict Fred and Daphne, are romantically connected in both the film and reality. For the first time in the franchise's history, the characters are shown as a couple in this film. Shortly after the film's release, the duo married. Prinze described his character as follows: "[He] was always more arrogant than the others. As a result, I took advantage of the chance in the film to make him as egotistical and self-loving as possible." [22]
