Wolfen is a 1981 American crime horror film directed by Michael Wadleigh and starring Albert Finney, Diane Venora, Gregory Hines and Edward James Olmos. It is an adaptation of Whitley Strieber's 1978 novel The Wolfen. NYPD Captain Dewey Wilson (Albert Finney) is assigned to solve a bizarre string of violent murders after high-profile magnate Christopher Van der Veer (Max Brown), his wife, and his bodyguard are slain in Battery Park. Executive Security, Van der Veer's client, prefers to blame the murders on terrorists, but knowing that the victim's bodyguard was a 300 pound Haitian with voodoo ties makes Wilson skeptical. At the crime scene, Wilson meets with Warren, his superior. With pressure to solve the case coming down from both the commissioner and mayor, Warren partners Wilson with criminal psychologist Rebecca Neff (Diane Venora). Meanwhile a homeless man goes exploring an abandoned church in Charlotte Street, South Bronx, which was going to be demolished by Van der Veer along with the rest of the ruined buildings in the area, in order to build new apartment complexes, and is suddenly attacked and torn to pieces by a monstrous being.
