I've just got confirmation from a Laserdisc collector in Italy and he says that THX on Laserdisc only exists in English NTSC (from US) and PAL (from UK). There are no Italian, German or French version of the film on Laserdisc.

So the best we can find is a tape that has not deteriorated. We can forget a high quality version of the recut.

Sorry guys, the person who told me he had a THX laserdisc perhaps didn't say that it was only in English.

erri_wan, thank you very much for offering your comments about this. I have always been fascinated with non-U.S. versions of the films I treasure. Thanks!

Wait till you watch it subtitled then! Plenty of differences.

Partially due to Warner's plot choices, partially due to a lousy localization of the Italian dubbing team.
