House on the edge of the park aka La casa sperduta nel parco Check on IMDB
When Ruggero Deodato, the director of über-controversial CANNIBAL HOLOCAUST, teamed up with David Hess, the notorious -“Krug”- star of The Last House on the Left, their maverick talents exploded in the feat of unrelenting sleaze that is THE HOUSE ON THE EDGE OF THE PARK.
Alex (Hess) is a psychopath and his friend Ricky (Giovanni L Radice) an easily led simpleton. When the unlikely pair are invited to an upscale house party where they are ridiculed by their debauched young hosts, Alex decides that he and his straight edged razor deserve some fun. Together the two streetwise punks take the unprepared partygoers on a journey of violence, debasement and forced sex. And that’s before events turn really nasty…
Deodato’s unwavering gritty direction keeps the tension unbearably tight and the psychological nuances of Hess and Radice’s powerhouse performances deliver uncomfortably challenging scenes so close to the bone that this originally banned Video Nasty remains one of the most contentious pictures in UK censorship history.
