title of a 1981 horror film starring Albert Finney, Diane Venora,
Gregory Hines and Edward James Olmos based on Whitley Strieber's 1978
novel The Wolfen. It was directed by Michael Wadleigh and the screenplay
was by David Eyre, Eric Roth (uncredited), and Wadleigh. NYPD Detective
Dewey Wilson (Finney) is assigned to solve a bizarre set of violent
murders in which it appears the victims were killed by animals. In his
investigation, Wilson learns of an Indian legend about wolf spirits, and
that there may be predatory shapeshifters living in the vicinity. The
film is known for its early use of an in-camera effect to portray the
subjective POV of a wolf. Similar to thermography, the technique was
later adopted by other horror films such as the Predator series.
