Did you know that this scene was entirely unscripted? Johnny Depp just kinda went with this and no one stopped him, so the reactions’ on the other actors’ faces are their actual reactions to Depp’s shenanigans.
makes the scene 100000 times better omfg
you can even see orlando glancing at the people behind the camera as if asking what is going on
Johnny improvises most of his scripts. And Orlando was actually told pretty much nothing for PotC to get his natural reactions.
