In Star Wars (ANH), there is the scene where Vader and Tarkin are told that there was nothing but some leftover equipment at the base on Dantooine. When the lines are read, everything matches up except (atleast in the non-SE) Vader makes an awkward hand gesture and there is a pause to show it. This is how it plays:

TARKIN: She lied! She lied to us!

VADER: I told you she would never consciously betray the Rebellion.

<Hand gesture and pause to show it>

TARKIN: Terminate her...immediately!

So, does anyone know what Prowse said here, or if he just delivered the line slower than JEJ or what? It's always bugged me.

I'll try to get a screen cap or some video later.
