Il testimone deve tacere
That’s right El Topo, yeah.
Grazie mille Corbett.
Never seen it (somewhere in my watchlist whatever that is), but recognized Daniele Vargas distinctive face.
Let’s try this one
More Dead Than Alive ?
Sorry Ennio to answer so late
But yes of course that the one, no need for the Vincent Price pic. A nice little western by the way
Up to ou now
Cheers, what about this one:
Sentivano uno strano, eccitante, pericoloso puzzo di dollari 
Thats correct Jonathan ! 
Thanks ENNIOO, here’s an easy one:
Two more…
First one looks familiar, I just can’t come up with the title. Death Laid an Egg maybe?
No Bill, not that one: it is a slightly different kind of film, a well-known Italian production from those years.
The Conformist?
Not that one, Rutledal.
Pic 3 shows a key element… 
Closed Circuit?
No Ion Britton, it’s not Montaldo’s movie.
Murder Obsession from Freda
Not at all El Topo, Bill and Rutledal were closer in terms of release year!
Investigation of a Citizen Above Suspicion?
