'Cold Eyes of Fear' (1971) - Enzo G. Castellari.

Maestro, Enzo G. Castellari's paranoid,darkly erotic, razor-edged Giallo has a stridently sinister, Ennio Morricone score, a raw, genuinely disturbing turn from a masterful, Frank Wolff, and contrary to the many naysayers, Castellari's stark claustrophobic thriller has much more to offer than, Gianni 'Sartana' Garko's strangely voluminous hair! And hack writers look out!!!! as vivacious beauty, Giovanna Ralli's steely strumpet sure 'aint got no heart of gold! The increasingly volatile, tripwire taut terror trip, 'Cold Eyes of Fear' excitingly remains an exemplary 'home-invasion' Giallo, the electric atmosphere positively seethes with a barely restrained bellicosity!
