KG is a movie tracker for rare, arthouse, and foreign movies, so they have a lot of Italian films (a little over 2,000). If you're looking for English movies dubbed/subtitled in Italian - they would not have that as it is not a specialized Italian tracker.
As far as I know, there are very few private Italian trackers and they were all pretty bad - the only I haven't checked out (that I've heard of) was Bit-Vault, and I've signed up for quite a few since I started torrenting. I found ColumboBT to be the most helpful for me, personally, but I was only looking for music and some other movies KG didn't have.
If there's something more specific that you're looking for that you can't find, it might be easier to use a different type of file-sharing - like eMule for example? I'm not too sure any specifics, but there are some Italian movie eMule sites around.
