So, it seems that Pirates of Caribbean 5 title will be "Dead Men Tell no Tales", which seems appropriate for a POTC movie, isn't it? What really surprises me is that they didn't used this quote as a title before! That said, i sincerely hope that the script of this POTC 5 will be better than the one of the POTC 4 movie. So far, for me the best remain the first one. There was good things in the 2 and 3 but i still think they should have done one movie with the POTC 2 and 3, instead of two.
Anyway, in the meantime you can have a look at this Pirates of Caribbean fan film which is quite well filmed in islands locations, even if the script is in my opinion a bit weak. It last 9 minutes and it's in french but with english subtitles.
