During a recent interview we had with Producer Jerry Bruckheimer for Pirates of the Caribbean: At World's End, we also talked with him about National Treasure: Book of Secrets and the action adventure film Prince of Persia.

Can you talk at all about National Treasure: Book of Secrets?

Jerry Bruckheimer: Yes, I can. Its really about the 18 pages that are missing out of John Wilkes Booth's diaries. That's all I can really tell you. Its based on history.

What about Prince of Persia?

Jerry Bruckheimer: Well, we're still working on the screenplay.

Pirates of the Caribbean: At World's End sets sail in theaters May 25 from Walt Disney Pictures.
