Let me clear up a few things about POTC2 auditions
Ok, here's the deal guys: It is HIGHLY unlikely that the director will be looking to cast an army of screaming fangirls (or fanboys for that matter) anywhere in his movie. Auditions will really only be held for speaking roles, and unless they hold open auditions (again, unlikely), you'd need an agent to represent you. Agents are expensive, so please don't go hiring one just so you can be in the same space as Orlando Bloom. ESPECIALLY if you've never acted before.
Now, there is a chance that the director will be looking for extras for the movie. Those kinds of parts wouldn't require audition. The problem with that is, unless I'm terribly mistaken, they're filming in the Carribean. If not, they're filming on one of their soundstages, which would mean you would have to live near there to be an extra.
I don't want to knock everyone, in fact I encourage you to try for the extra thing, I just didn't want you all getting your hopes up in order to have them knocked down later.
