Q is one of those films with a confusing plethora of names. In the United States, it was first known as The Winged Serpent. Later it was retitled simply Q (short for Quetzalcoatl, the Aztec god who was half reptile, half bird); in Britain, it was known more formally as Q - The Winged Serpent. The director Larry Cohen is a famed writer/director/producer of exploitation films, among them Demon, It’s Alive! and The Private Files of J. Edgar Hoover. Q was his most ambitious film, a combination of slasher movie and King Kong. In fact, Cohen goes one better and sets his monster’s roost, not in the Empire State Building, but in the attic of the Chrysler Building.
