Bill Nighy Addresses Pirates 4 Rumors

Actor Bill Nighy (Davy Jones in POTC and will appear in Harry Potter and the Deathly Hallows) talked to Sci-Fi Wire about things he heard about Pirates of the Caribbean 4;

"I understand that there was an announcement that there was going to be a fourth, and now I've been told since that that was not a reliable announcement,
"I'm pretty sure that there will be [a fourth], I would be amazed if there weren't, given the success of the first three."
