Four Flies is the weirdest one from the Animal Trilogy. Totally different framing and editing gives this one a bit of an experimental feeling to it. The whole thing also has a disjointed feel to it because of the jarring cuts, but it works nonetheless. There are also some non-giallo elements thrown into this one that further confirms the feeling that Argento experiments more with Four Flies than he did with his two first films. Not that it’s anything wrong with that. Four Flies is a fabulous film, and of the three films in the Animal trilogy, the most unique.

The story is quite good. Unquestionably a giallo, and you can really see that Argento had to have had more time to perfect this script, unlike The Cat. This one, like both the previous two films, has less focus on the violence and more on our main man's confusion and feeling of not knowing what the hell is happening around him.

As fas as the acting goes, it’s decent, but more uneven than both The Bird and The Cat. Michael Brandon is a bit lacking in the lead role, but it doesn’t really ruin anything. Mimsy Farmer as the lead's better half works a lot better, and is my favourite from Four Flies.

Ennio Morricone’s third score for Dario Argento is just as understated as in The Cat, and really disappears in most scenes, but it works better than I remember it. I don’t know if it is Argento's heavy use of music when he starts to collaborate with Goblin that colour my opinion, but I prefer the scores he made with them over these, more understated, ones.

I really like Four Flies on Grey Velvet. It’s not as “important” in the grand scheme of things as The Bird with the Crystal Plumage, but in many ways, it’s just as good. The only thing that makes me rate this a bit lower, is that I like the acting performances and music a bit more in The Bird. Four Flies is also essential viewing when it comes to Argento, and should not be missed.
