Johnny Depp, the star of the film, is so committed to the role, he's keeping in the gold teeth sported by his character, Captain Jack Sparrow. "Are they gonna stay on?" he said to MTV News. "Only until we're done filming number three. Then I'll have to go through the process of yanking them."
As for offering any hints about the twists and turns of the third movie's plot, the stars have been coy.
"I am so not going to say anything!" Keira Knightley told MTV News. "I'd have to kill you if I said anything. It would be very messy."
Knightley added, however, "It should be good, though."
"It's supposed to be that we're lovers," said Harris. "We talked about it in rehearsals, but Gore (Verbinski, the director) left it up to us, really, to come up with our own stories ourselves."
The third installment, which is scheduled to be released next Memorial Day, will resolve the story line between Orlando Bloom's character, Will, and his father – as well as offer a cameo role for Rolling Stones guitarist Keith Richards, who will play Sparrow's dad.
In any case, the swashbuckling cast isn't taking much time to enjoy the enormous success of the second film before starting the final one. "We're going back soon," Orlando Bloom told MTV. "We're going back to film three more months."
Filming will resume in August, reportedly at Universal City in Hollywood, where an enormous Pirates set awaits to be plundered.
