To be fair to negative 1 the dialogue is different in the final film than in the shooting script.

You want the llines as they were delivered in the film you need the transcripts aka continuity scripts.

Which were sold in the uk seperately and also came with the executor boxset which i have.

There are 2 versions of the fourth draft script out there.

The real shooting script which appears to be the same source Alan Dean Foster used for the novel, and the published final script.

It was first released in the art of star wars book.

Even the premiere magazine script still contains the deleted biggs scenes and the Jabba scene.

The scripts that have been released or leaked out are over at the starkiller site of the jedi bendu.

Just type starwarz.com and youll find the link there.
