Director Jon Turteltaub:

"If you can write the script, we’ll take it!  It’s so [exceptionally] hard to write a great historical mystery based on fact.  It’s not for lack of trying.  We want to do the movie.  Disney wants to do the movie.  We’re just having [a difficult] time, writing it."

"I’ll bet that within two years, we’ll be shooting that movie."

"We’re closer.  I’d say we’re about half-way there.  It’s not only writing a great historical mystery, but we’ve gotta write something that has nothing to do with anything we’ve done before.  The goal is to always have an original sequel, as silly as that sounds.  We really want to make sure that the third one doesn’t just feel like a repeat of the first one, or one too many."
