Freddy vs. Jason Freddy vs. Jason Freddy vs. Jason (alternatively known as A Nightmare on Friday the 13th) is a 2003 American slasher film directed by Ronny Yu and written by Damian Shannon and Mark Swift. The film is a spin-off crossover between "A Nightmare on Elm Street" and "Friday the 13th" series, and pits Freddy Krueger and Jason Voorhees against each other in the eighth and eleventh installments in their respective series. The film is also the last in both "A Nightmare on Elm Street" and "Friday the 13th" series before they were both rebooted. In the film, Freddy (Robert Englund) has
Jason Voorhees "The New Blood". Since Jason had been submerged under water in the previous entry, the effects team wanted Jason to appear "rotted", with bones and ribs showing, and for Jason's features to have a more defined feel to them. Howard Berger was inspired by Carl Fullerton's design in "The New Blood", and wanted to incorporate the exposed flesh concept into his model for "Jason Goes to Hell". Berger designed Jason's skin to overlap with the mask, to make it appear as if the skin and mask had fused and the mask could no longer be removed. Gregory Nicotero and Berger
