The Last House on the Left (1972)

In Wes Craven's controversial early low-budget horror film, a taboo-breaking and often revolting 'snuff'-type film:

• the film's sensational opening titles sequence - teenaged Mari Collingwood (Sandra Cassell) in the shower preparing to go out with her friend Phyllis Stone (Lucy Grantham) and search for pot while on their way to a Blood Lust concert
• the long ordeal of the two teenaged girls who were kidnapped by a group of escaped convicts led by Krug Stillo (David Hess); Phyllis' dark blue blouse was opened to expose her breasts, and then Krug punched her in the stomach and raped her
• their brutal and sadistic torture, rape, dis-embowelment, and eventual murder in the woods -- blue-wearing Phyllis was forced to urinate with her clothes on ("Piss (in) your pants...Do it!") - the camera panned down, showing her wettened blue-jeans

Mari and Phyllis

Phyllis Ordered to Piss In Her Pants

Forced Oral Sex

• the two females were stripped naked and forced to have oral sex with each other ("Make them make it with each other!") - as the girls rationalized: "lt's just you and me here. Nobody else. Just you and me, okay?"; psychopathic, sadistic gang member Sadie (Jeramie Rain) also performed oral sex on Mari
• the scene of Phyllis making a run for it, but was cornered, stabbed in the back by deviant Fred "Weasel" Podowski (Fred Lincoln) and then dis-emboweled (after repeated stabbings) and butchered, after which Sadie reached in and pulled out her gooey intestines to examine them - Phyllis' left hand and half of her forearm were amputated (off-screen)
• the brutal sequence when Mari had Krug's name carved into her upper chest and was then brutally raped (as he drooled onto her face); she vomited and then walked dazedly into a nearby pond to half-submerge and cleanse herself where Krug shot and killed her, and she floated on the water's surface

Mari's Ordeal

• and the later sequence of animalistic payback revenge/slaughter by the Collingwoods on the gang (who had been seen in intercut segments, planning a 'surprise party' for Mari) -- the father (Gaylord St. James) semi-electrocuted Krug, chipped out his teeth out with a chisel (in a dream sequence) and pursued him with a chainsaw and killed him (off-screen, evidenced by blood splatter)

Father's Pursuit of Krug with Chainsaw

• meanwhile outdoors, the mother (Cynthia Carr) cleverly enticed gang member "Weasel" to have sex (she had also convinced him to have his hands tied behind his back) - he told her: "Now you just unzip me, and that's all l'll need you for"; at first, his penis ("little thing...poor little fellow") became caught in his zipper and he was unresponsive, but as she touched him more and more, he warned: "lf you don't watch it, l'm gonna come"; she urged: "Please come then, sweetie"; he asked: "Don't you want me to do you good and proper?" - she replied: "You can do both, can't you?" - he boasted: "Hell, yeah! I can come five or six times if you want me to"; she sank down to crotch-height, and as he was climaxing, she viciously bit off and dismembered his penis; after returning home, she fought off Sadie with a knife, and then was able to slash her throat with the weapon in the pool
