Eyeball

Although mostly known for his bloody jungle-set cannibal films (Cannibal Ferox; Mangiati Vivi) and the splattery zombie-adventure Incubo sulla Citta Contaminata, Italian filmmaker Umberto Lenzi also made a number of interesting thrillers, including this engagingly incoherent giallo about an eyeball-stealing killer. The slayer's handiwork is first revealed when a female member of an American tour group is stabbed to death in Barcelona, and a teenager on an amusement park ride is murdered in a similar fashion the following day. Coincidentally (or perhaps not), a businessman named Mark Burton (John Richardson) finds out that his wife, Alma (Marta May), is in town, and remembers finding her unconscious once back in America with a human eyeball lying next to her. More murders follow, with a peasant girl, a lesbian named Lisa (Mirta Miller), and her lover (Ines Pellegrini) all attacked by the raincoat-clad killer. After yet another attack, Mark falls under suspicion, and must discover the killer's identity in order to clear his name.
