Part psuedo-documentary about the Italian counterculture and drug scene (Dr. Humphry Osmond appears as himself) and part straight up LSD exploitation film, Acid Delirio Dei Sensi (“Acid, Delirium Of The Senses”) is an obscure Italian cult movie directed by Giuseppe Maria Scotese. The plot involves some free-livin’, free-lovin’ hippies who get mixed up with the Mafia.
 

 
Acid Delirio Dei Sensi is one of those films best known for its poster art—some examples here—which is highly collectible and molto expensive. The little-seen film itself, however is surprisingly decent.
