The Texas Chain Saw Massacre, made in 1974, has topped a poll of the greatest horror films of all time.
A remake of the film was released in 2004
The gory classic topped a poll by movie magazine Total Film.
Made for just $140,000 US dollars, it is based on the exploits of real-life serial killer Ed Gein and stars Gunnar Hansen as the axe-wielding Leatherface.
"The only thing more terrifying than the opening 50 minutes of The Texas Chain Saw Massacre is the last 30," the magazine said.
The movie was refused a certificate for many years for its depiction of violence and was one of the original crop of films termed a "video nasty".
Halloween, starring Jamie Lee Curtis, was second in the list while third was 1970s Italian shocker Suspiria, followed by Dawn of the Dead and The Shining.
