the return of ringo (1965)

aka Il ritorno di Ringo.
"A man who is not afraid can only die once."
Montgomery Wood (Giuliano Gemma) is a soldier who returns home to find his family murdered and his property taken Mexican bandits. With nothing left Wood goes undercover disguised as a Mexican, hell bent on revenge, but then he finds he has a daughter!
Interesting take on the revenge story, with the hero being much more reticent and thoughtful than most.

death occurred last night (1970)

aka La morte risale a ieri sera. Death Took Place Last Night.
"Does your wife know what it takes to turn you on?"
When a beautiful, but mentally retarded woman in her twenties disappears, police chief Duca Lamberti (Frank Wolff) tries to find her. But when her body turns up, they enter a race to find the killer before her father (Raf Vallone) does.
With the look of a gritty crime drama, this Giallo plays out more seriously than most, and is all the better for it.

big guns (1973)

aka Tony Arzenta: Big Guns. No Way Out. Tony Arzenta.
"When your mind is made up, it stays made up."
Family man Tony Arzenta (Alain Delon), is actually a hit-man, but with his son growing up he wants to change occupation. But will his bosses let him? The answer doesn't take long in coming, as his car explodes with his wife and son in it. Now with nothing to lose Tony only has thoughts of revenge.
Good little thriller, that's driven along at a fair pace, preventing any chance of boredom.
