Nope, neither Keira nor Orlando thought it was necessary to continue their characters since their story pretty much ended. Of course Jack and Barbossa will be in it with possibly penolpe cruz I believe.
No, there won't be Will nor Elizabeth. They thought it was pointless to continue their stories since it was pretty much over. Also, the actors wanted to try different movies. Penelope Cruz is supposed to be "Jack's equal and foil in many ways" according to "The Johnny Depp Zone." If you're interested in new info about Johnny Depp (which is گیا کیا پوسٹ almost every day) then go to The Johnny Depp Zone for مزید stuff, which also includes a weekly picture that's added every Saturday!!! HAVE FUN!!! ;P --i guess.....
