Good spot.

I think it was inherent in the editing techniques of the time....probably due to a torn frame in the OCN....if it was ripped or unusable...they spliced it out.

I noticed a similar jump cut in Raiders of the lost ark.

It occurs when Indy is describing the ark to the 2 Army intelligence officials in the school hall.

Observe when Indy says:

"yeah the Ark of the covenant....the chest the Hebrews used to carry the 10 commandments in ".

Now I only noticed it when I was projecting the blu ray onto a screen of 77inches.

But then I thought I would double check my original 1983 V2000 Raiders video tape to see if it was always there...and sure enough it is!
