Apparently, an article about dubbing the new scenes in the SE was printed in 1997 in "Les Années Laser", a French magazine about home cinema.

There was a history of "who dubbed what and how" and also an interesting statement about the sound of the French LDs being plain stereo and not Dolby Surround because the original 1977 French mix for the movie was only a 2-channel stereo mix due to limitations of French theaters at the time. (Same statement appears on the lddb listing here).

Do you have more information about this article and when it was release ? Are you sure it was in "les années laser" ?

Because I'm searching this article but didn't find it.

BTW, I'm sure "Heidy Webel" is a typo, since she's credited as "Heidi Weibel" in the German credits. Looks like she was responsible for several international dubs then.... and her name sounds pretty much German.

You are certainly right. The interviewer had to misspell the name
