Okay, so which Italian crime films bear the most giallo influence or are the biggest genre hybrids? We've discussed this here and there, but let's compile a definitive list. I'll start the ball rolling with:
Blazing Magnum/Una magnum special per Tony Saitta
The Maniac Responsible/...a tutte le auto della polizia
The Perfect Crime/Indagine su un delitto perfetto
(okay, so this isn't really either crime or giallo, but I'm throwing it out there, because it's sure to come up)
