The fourth installment of the Pirates of the Caribbean series will be released in 2011. It is based, in part, on the award-winning 1988 novel "On Stranger Tides" by celebrated Fantasy/Magical Realism author Tim Powers. It combines piracy with the supernatural, a perfect fit for the PotC franchise. Do yourself a favor and read this book while you're waiting for the movie to come out. We only wonder if they kept Blackbeard in the film script. Powers himself speculates that Blackbeard's role in the tale will be taken on by mutinous first mate Barbossa.
