Trivia: In Lori's dream, kids teasing a young Jason place a burlap sack on his head, similar to the burlap sack Jason wore in Friday the 13th Part 2. Jason started wearing the goalie mask in Friday the 13th part 3. (00:08:00)
Revealing mistake: When Linderman dashes at Jason and impales him with an American flag, Will is dragging Lori (who is supposed to be unconscious). He's dragging Lori by her arms... but when he suddenly reaches behind his back with his right arm, her right arm stays up in the air. (01:13:50)
Continuity mistake: When Freddy and Jason get hit by the cart at the construction site, they land next to each other on the dock. But in the next shot, we see Jason getting up quite a distance away from Freddy. (01:20:10)
Revealing mistake: When the drug "Hypnocil" is researched on the Internet, an article about the drug appears. If you pause the shot and read the article, you can see that it has nothing to do about Hypnocil. The article is about drug testing of students who engage in extracurricular activities. (00:55:10)
Answer: This is one of those questions where we'll probably never know the real reason because different people involved have different stories as to why Kirzinger was picked over Holder. Holder himself has said he doesn't know why he didn't reprise the role, especially since he was told he would and was given a script. Some accounts say Yu wanted Jason to tower over Freddy and Kirzinger is 2" taller than Holder. One of the casting directors said Yu thought Holder's version of Jason was too campy. Meanwhile, Yu said it was New Line Cinema's decision to recast Holder because they want to change the direction of the film and used this film as a reboot of the series.
