If you like 70's-80's Italian genre films,you'll like Stridulum aka The Visitor (1979) I think.

It's also the best dvd around of this one,I also have the Italian dvd and the Code Red has superior pic quality.
Both have the uncut international version featuring (an uncredited) Franco Nero in the opening sequence and more Sam Peckinpah and Glenn Ford amongst other things.
