User blog comment:J Fan/Latest Pirates 5 news as of October 2014!/@comment-3106883-20141019094810

I'm delighted that Pirates 5 is being filmed in my own country. For one thing, news on the film should be easy to find, and through the main news agencies, rather than entertainment news.

I don't trust the entertainment news about this franchise. It seems true that Bardem is in TALKS about playing a villain, but other than that everything in your Unconfirmed list seems to be guesswork or their own wishes rather than sourced information. Especially that bit about Blackbeard possibly returning.
