Forty years after it scared the pants off America — and territories beyond — Tobe Hooper’s ultimate scare machine The Texas Chain Saw Massacre is returning to the big screen this summer in freshly restored form. Hooper himself worked on the restoration and recently told Entertainment Weekly “the film works as well, if not better, than it originally did.”

Will the filmmaker’s classic tale of cannibalistically-inclined lunatics and the college-age kids they try to turn into barbecue wow a new generation of cinemagoers? That remains to be seen. But we can say that, four decades after Hooper and co-writer Kim Henkel first introduced us to Gunnar Hansen’s Leatherface and the rest of the film’s demented crew, the brutal trailer for the restored Texas Chain Saw Massacre is not one for the faint of heart nor weak of stomach.
