I didn't say it's "always allowed". There are difficult directors with very specific vision they want to express 100%. It's that that is the exception and not the rule, however.
In general it's more common that some lines will change and be improvised by the actors, than not.
It's even practical, some lines come off as stiff when the actors tell them verbatim, others just can't be replicated in a longer emotionally charged scene (where the flow and the emotions carry the performance), and so on.
>Often others higher up have the final say. If he wants you to say the line as written, you will say the line as written.
