Sahara (2005)

Master explorer Dirk Pitt (Matthew McConaughey) takes on the adventure of his life when he embarks on a treasure hunt through some of the most dangerous regions of West Africa. Searching for what the locals call "The Ship of Death," a long lost Civil War battleship which protects a secret cargo, Pitt and his wisecracking sidekick (Steve Zahn) use their wits and clever heroics to help Doctor Eva Royas (Penélope Cruz) when they realize the ship may be linked to mysterious deaths in the same area.

Based on the best-selling novel by Clive Cussler.
