Trivia: While the film is primarily written by "Scream" and "Scream 2" writer Kevin Williamson, due to a hectic production schedule, "Scream 3" writer Ehren Kruger was brought on to do some last-minute rewrites during filming. However, Kruger chose to go uncredited, as he mainly worked on "polishing up" scenes originally written by Williamson.
Trivia: Something odd to notice: "Scream 4" is the only one of the four films to feature the iconic image of "Ghost-Face" (the name of the mask the killer wears) on the US poster or DVD cover. All three previous films had just pictures of the cast and the title arranged over a black background. (Although the DVD cover does retain this look, a profile image of Ghost-Face has been added into the background.) Somewhat ironic, as the films are so synonymous with the mask.
Trivia: "Scream 2" was released only one year after the original, while "Scream 3" was released three years after the second film. By contrast, it took an entire eleven years for the fourth film to come out. Originally, "Scream 3" was meant to be the final film in the series. Series director Wes Craven and series creator Kevin Williamson, along with producer Bob Weinstein, felt that given the increasing numbers of remakes and reboots that began to come out after "Scream 3", that it would be fun to make a fourth film in the series that satirized the concept of redoing old ideas. Thus, "Scream 4" was born.
Trivia: The final film of director Wes Craven, who tragically passed away from brain cancer in 2015. While a fifth film has been rumored in the years since this movie's release, series star Neve Campbell and series writer Kevin Williamson have said it would be difficult to do without their friend and director Craven at the helm, and have expressed doubts about wanting to be involved.
Trivia: Aspects of this film (including the motivation of the lead killer) were actually left-over ideas from Kevin Williamson's original plan for "Scream 3." After he was unable to commit to writing "Scream 3", a new writer was brought on who wrote an entirely new script. Williamson re-worked portions of the original "Scream 3" story-treatment into the plot of his television series "The Following", and then subsequently re-worked other portions of the story-treatment into "Scream 4."
Trivia: Something subtle many don't notice - the blade on the knife in many murder scenes is actually CG, with only the handle being real. This was done for several reasons - first, because rubber knives tend to look a bit "iffy" on-screen, second for safety and third, because it aided in the gore effects, since they could have the killer actually shove the handle into the victim and digitally animate the blade going in, making a more seamless stab effect possible.
