The Texas Chainsaw Massacre is a 2003 American slasher film directed by Marcus Nispel, written by Scott Kosar, and starring Jessica Biel, Jonathan Tucker, Erica Leerhsen, Mike Vogel, Eric Balfour, and R. Lee Ermey. Its plot follows a group of young adults traveling through rural Texas who encounter Leatherface and his murderous family. It is a remake of Tobe Hooper's 1974 film of the same name, and the fifth installment in The Texas Chainsaw Massacre franchise. Several crew members of the original film were involved with the project: Hooper and writer Kim Henkel served as co-producers, Daniel Pearl returned as cinematographer, and John Larroquette reprised his voice narration for the opening intertitles.
