I don't know but the scene you refer to I think is in the movie, the sound heard in the background (Luke groaning) is not or the sound quality augmented it so that it sounds different. Or they added another sound for the trailer.

I have my own question following my previous poster:

I love this project and I've following it for about 3 weeks. I realize that this is a restauration of a original Technicolor print reel, from the original movie that was probably in the cinemas back then when the movie was released.

Did the original theatrical release, or does this Technicolor print contain any scenes or alternate takes that were NOT present in the first home entertainment release for this movie (VHS or 8mm prints).

I see that George Lucas had a urge to change things spontaneously or post work. So do many other directors and there are many classic movies that were slightly different on their first theatrical release and on their first home entertainment release. When Empire Strikes Back came to cinemas nobody knew that Darth Vader is gonna say "I'm the father!".

Blade Runner is probably another good example and there are many more movies.

There are just a few bits and takes altered from it's original theatrical presentation.

I wanted to ask if this is true for Star Wars? I've never seen the original (really original!) theatrical.

Or was the first home release (VHS) an exact print of what was shown in the cinemas?

Can I expect to see ANY greater or minimalistic changes, like alternate timing, or sounds, alternate takes? That would be very interesting to know.
