Veteran slashers Freddy Krueger and Jason Voorhees join forces in this combination sequel to the NIGHTMARE ON ELM STREET and FRIDAY THE 13TH series. The film begins with a quick recap of both Freddy and Jason's "lives," underscoring their respective motivations to kill and their distinct weaknesses. Freddy (Robert Englund) explains that the present children of Elm St. (including Monica Keena, Jason Ritter, Katherine Isabelle, and Kelly Rowland of Destiny's Child) have no memory of him, and if they don't know he exists, he can't enter their dreams to kill them. Ingeniously, he reaches out to Jason (Ken Kirzinger), the brutish death machine from Camp Crystal Lake, to go on an Elm Street killing spree, hoping a lot of gory murder will jog the town's memory. Jason is up to the task, quickly dispensing with teenager after teenager in suburban homes, cornfields, medical labs and, of course, the forest. Freddy grows jealous over Jason's body count, and so must intervene, setting off a battle royale between the two highly adored slasher heroes across dreamworlds and realities. In another post-modern twist, a character seemingly modeled after Jay from Kevin Smith's films appears in the movie, adding both a comedic element and another level of reality vs. fiction. FREDDY VS. JASON employs a variety of special effects to update these undying series, not the least of which is uniting their once disparate stories.
