Jabarkan Giallo dari Film jagal

Pengaruh film jagal lain adalah sub-genre darinya, yakni genre Giallo. Genre film ini dibuat oleh film-film yang dibuat banyak sutradara Italia, yang paling sering dan terkenal adalah Dario Argento dan Mario Bava. Film-film ini bisa diketahui dengan adegan pembunuhan dan plot yang mengerikan yang lebih komplet dan banyak dibandingkan film jagal. Film giallo yang paling terkenal salah satunya adalah Blood and Black Lace (1963) dan Twitch of the Death Nerve (1971) karya Mario Bava. Beberapa kritikus memberi catatan bahwa film-film ini juga memberikan pengembangan baru baik dalam sub-ragamnya maupun ragam jagal sendiri. Ditulis pada tahun 2000, Tim Lucas menulis bahwa Bava adalah “the acknowledged smoking gun behind the ‘body count’ movie phenomenon of the 1980s, which continues to dominate the horror genre two decades later with such films as Scream, I Know What You Did Last Summer, and their respective sequels.” Menurut Gary Johnson, “Twitch of the Death Nerve is one of the most imitated movies of the past 30 years. It helped kick start the slasher genre….[Bava’s] influence still resonates today (although somewhat dully) in movies such as I Know What You Did Last Summer, Scream, and Urban Legend.”. Johnson juga menyatakan bahwa Blood and black Lace adalah "Equipped with his colored gels and his predatory camera, Bava arguably created the slasher subgenre and kicked down the door for subsequent directors to stick in their cinematic blades as well, for better or worse. Hitchcock toyed with us, Powell showed us but kept his emotional distance, but Bava passionately reveled in the shock of it all. Camera as weapon; the masked killer as cipher upon whom the audience was almost gleefully invited to imprint their darkest animosities. " Film Amerika tahun 1992, Knight Moves dideskripsikan secara online bahwa itu adalah film giallo barat dengan elemen-elemennya yang sama.
