From the Dark Horizons website:
Novelist Clive Cussler's PR representative recently spoke about the
casting of Steve Zahn as sidekick Al Giordino in Paramount's upcoming
major adaptation - "Zahn came to Arizona and lobbied for the role and
convinced Clive Cussler that he could do it. More power to him! He
promised Clive that he would not only continue to bulk up, cut and dye
his hair but that he would learn to take apart and put back together
automatic weapons in record time...Zahn's knowledge of Civil War
history and antique fire arms along with his acting skills honed at
Harvard and on and off Broadway, convinced a skeptical Cussler that
Zahn could pull off the pivotal role". Thanks to 'BFD'
