kyra, house near the lake (1979)

aka Sensitività. Devil's Encounter. The House by the Edge of the Lake.
"Shall we go to the cemetery tonight?"
Student Lillian (Leonora Fani), visits her family's country villa, where years earlier her mother drowned in a nearby lake, and starts to research a legendary local witch.
At times atmospheric, but mostly baffling and incomprehensible supernatural thriller.

kill them all and come back alone (1968)

aka Ammazzali tutti e torna solo. Go Kill Everybody and Come Back Alone.
"What is it makes you think we can trust such a band of bandits, killers, and thieves?"
Almeria again becomes home to a western, this time set during the American Civil War, where a Confederate agent (Chuck Connors) is chosen by Captain (Frank Wolff) to hand picks a team to steal a gold shipment destined to buy the Union weapons. His orders also specify that his team are not to return with him, but they object to this caveat.
Lots of action, and some surprises along the way, make you forget that this is familiar ground, with the script mixing in bits from many other westerns.

cold eyes of fear (1971)

AKA Gli occhi freddi della paura. Desperate Moments. Los fríos ojos del miedo.
"I'll kill you."
Peter (Gianni Garko), a solicitor, has brought Anna (Giovanna Ralli) to his uncle's house, only to find Quill (Julian Mateos), and a dead body waiting for them. Quill takes them hostage, but its not them he's after but Peter's corrupt uncle Judge Flower (Fernando Rey). But what is he after?
The tension ramps up when policeman Arthur Welt (Frank Wolff) turns up with some papers from the Judge. The action is slow in coming as the main participants argue, threaten and cajole each other, but it develops into a tense hostage thriller, rather than a straight up Giallo, where no-one is what they seem.
