Italian director and crew and has been called a giallo in its own right. Gialli continued to be produced throughout the 1970s and 1980s, but gradually their popularity diminished and film budgets and production values began shrinking. Director Pupi Avati satirized the genre in 1977 with a slapstick giallo titled Tutti defunti... tranne i morti. Though the giallo cycle waned in the 1990s and saw few entries in the 2000s, they continue to be produced, notably by Argento (who in 2009 released a film actually titled Giallo, somewhat in homage to his long career in the genre) and co-directors Hélène Cattet and Bruno Forzani, whose Amer (which uses music from older giallis, including tracks by Morricone and Bruno Nicolai) received a positive critical reception upon its release in 2009. To a large degree, the genre's influence lives on in the slasher films which became enormously popular during the 1980s and drew heavily on tropes developed by earlier gialli.

In particular, two violent shockers from Mario Bava, Hatchet for the Honeymoon (1970) and Twitch of the Death Nerve (1971) were especially influential. Early examples of the giallo effect can be seen in the British film Berserk! (1967) and such American mystery-thrillers as No Way to Treat a Lady (1968), the Oscar-winning Klute (1971), Pretty Maids All in a Row (1971, based on an Italian novel), Alfred Hitchcock's Frenzy (1972), Vincent Price's Madhouse (1974), Eyes of Laura Mars (1978) and Brian De Palma's Dressed to Kill (1980). Berberian Sound Studio (2012) offers an affectionate tribute to the genre. Director Eli Roth has called the giallo "one of my favorite, favorite subgenres of film," and specifically cited Sergio Martino's Torso (I corpi presentano tracce di violenza carnale) (along with the Spanish horror film Who Can Kill a Child?) as influential on his 2005 film Hostel, writing, "...these seventies Italian giallos start off with a group of students that are in Rome, lots of scenes in piazzas with telephoto lenses, and you get the feeling they're being watched. There's this real ominous creepy feeling. The girls are always going on some trip somewhere and they're
