The script for PIRATES 5 is currently being rewritten by Terry Rossio. Also, Rob Marshall may be directing it.

Marshall has signed a two-year deal with Disney. (It involves him being director of an upcoming Disney film INTO THE WOODS.) He’s staying up-to-date on the development of Pirates 5, although he has not officially committed to being director yet. Along with Johnny Depp, Marshall seems to be waiting on a finished script before he commits to the film.

What Rob Marshall has to say about Pirates 5:

“Terry [Rossio] is writing it and he’s working incredibly hard and he did a draft and rethought it all and started working on it again. You want to make sure you are asking the audience to come back to see an exciting adventure and it has to reach that caliber, and if not there’s no reason to do it. I know Johnny feels the same way: He needs to see a script, but he would be happy — if it’s the right script — to put that hat and sword back on.”

EDIT: It seems that I caused a little confusion because I misread the articles. Oops! Marshall’s two-year Disney deal just involves him directing Into The Woods - NOT The Thin Man. The Thin Man will be produced by Warner Bros.; Marshall is still directing it though, with Johnny to star in it. :) With that being said, I corrected what I previously wrote. Sorry about that!
