I see a lot of talk online and get asked about giallo quite frequently. It’s such an overwhelming genre and it’s hard to know where to start.  Typically people recommend Argento and Bava but that is just a small sliver of this amazing method of storytelling. Here is a very long list of gialli for you to consume. This list contains straight forward gialli, neo-gialli, and gialli adjacent films that you should check out. Even some of the lower rated ones have something to offer and I suggest you watch them to make up your own mind or create your own list. This list was difficult to do because some of these films are a little bit of a stretch to include on this list but I feel they are pretty well grounded in that gialli world.
