I have now seen what thxita sent me, and it's the same dub on at least the intro, which is what the clip is:

This version starts with the American Zoetrope logo and have exactly the same editing we are all used to from the original. It is the regular american cut for at least the first few minutes.

But here's what's interesting; the narration and car chase that opened the other Italian cut, is present. But only in audio obviously over the titles. The same prologue narration, it just continue over all the extra footage montages that was cut from the previous Italian version and ends at the same time perfectly with THX. There's an 80's home video logo at the start - the blue and white one. This is most likely the version that's on the tape I bought, sorry haven't been able to check what's on it yet but hopes to do that sometime next week.

I'm about to upload this clip for you Leo and Silver as I type so you can see and hear it for yourself.

For anyone else interested in the clip, give me a PM.
