Sam's Strange Sentence

[Rinfanawen]

I was browsing through a movie script today and came across something quite odd in the process. I was looking at the FOTR script near the part where Frodo meets Aragorn at Bree. Here is a line, said by Sam, and this is how it was written...

Sam: Stand off! /Let him go! Or I’ll have you Longshanks! [Note to reader: these are the two different versions heard by audiences everywhere]

Has anyone came across an edition where the line is said, "Stand off! Or I'll have you Longshanks!" ? I was just curious if the version was made for countries foreign to the US, or if there is a separate version out there somewhere in my own country. Any help?
