not to mention the first 20

Well I made the purchase, loved the movie and now am on the hunt for Inferno.

Opera and Tenebre are really cool as well

which 'opera'?

http://imdb.com/title/tt0093677/

this one

i see. my copy is called terror at the opera. i'm in the middle of watching it. so far so good. like suspiria its visually stunning. i'll finish watching it tonight.

Hmm... Well let me know how it is I was hesitant when I first heard about it but the more I get into Argento's work the more I want to see every film he has had a hand in.

heres my list of argentos and i can honestly say i'd recommend all but trauma: suspiria, tenebrae, profondo rosso, the cardplayer, stendhal syndrome, sleepless, trauma, the church, terror at the opera, the phantom of the opera, demons, two evil eyes. i hope i'm not patronising you but many of his movies are 'giallo'. the genre of italian, violent, murder thrillers. you should seek recommendations for other movies in this genre if you enjoy some of his other work. suspiria isn't a giallo and many giallo directors frown on their movies being termed horror but they are good quality none the less.

What have you seen so far?

Well at the moment I have only seen Demons 1,2, and 3, Suspiria, and Deep Red. I must say though I have loved it all with the exception of Demons 3... I enjoyed it and all just no where near as much as the first two. I also just recently have "discovered" Italian cinema and just got done watching Fulci's Zombie, and finally got to see the infamous "Zombie vs. Shark" scene. Although at this moment in time I am on the hunt for Inferno. Any suggestions for what I should watch afterwards?
