I didn’t know that so thanks for sharing the info. The wikipedia article confirms that.

However, it would be inaccurate to think that was the only reason. It’s an important reason, but there are other factors too. I’d guess one being the financial costs of dubbing. Also, there are other European countries which don’t have a tradition of dubbing and never had fascist regimes.

Be it as it the theme that made me start this thread is

the fact that the 1991 broadcast of SW was in widescreen, which apparently might have been a world premiere?
the fact that the only screen captures I got hold of seem to cover a different area of the film. It doesn’t match the oldest widescreen source I have which is one fan preservation of a Laserdisc realease and I don’t know whether it’s first widescreen one or the THX remastered. I’m not on myspleen (would love to join but that seems impossible at the moment) so this preservation was the only thing i managed to grab which is can be found on public sites.
