The Texas Chainsaw Massacre has topped a poll by movie magazine Total Film of the greatest horror films of all time.
The chilling 1974 classic is based on the killing spree of real-life serial murderer ED GEIN and was made for just $140,000 (GBP78,000).
The 1970s was labelled the best era for film horror, boasting six of the list's top 10 titles, including The Texas Chainsaw Massacre.
The slash movie was initially denied certification for star Gunnar Hansen's unflinching portrayal of extreme violence.
The chart compilers said: "The only thing more terrifying than the opening 50 minutes of The Texas Chain Saw Massacre is the last 30."
