Seven Beauties (1975, It.) (aka Pasqualino Settebellezze)

In director Lina Wertmuller's tragi-comic war film (she became the first Oscar-nominated female director for this film):

• the dream-like opening credits sequence with a jazzy tune (repeating the refrain: "Oh yeah"), about man's inhumanity to man throughout history (with stock WWII documentary photos of Mussolini and Hitler, bombs, and trench warfare)
• the character of small-time Naples crook Pasqualino Frafuso (Oscar-nominated Giancarlo Giannini) who had to support his many ugly sisters and mother
• his time in an insane asylum (where he raped a bound madwoman) after murdering and dismembering the pimp who coerced his sister into a life of prostitution
• the scenes in a WWII Nazi concentration camp when a desperate, debased and unscrupulous Pasqualino traded sexual favors with the grotesquely-obese, whip-wielding commandant (Shirley Stoler) for survival (she told him: 'You have found the strength for an erection, that's why you'll survive") - but he also chose those to be executed (and also killed his best friend)
• the film's final shot - in closeup - of Pasqualino returning home and his sadly-spoken words to his mother: "Yes, I'm alive"
