The Mummy: Tomb of the Dragon Emperor stars Brendan Fraser reprising his role as explorer Rick O'Connell, along with his son Alex (Luke Ford), wife Evelyn (Maria Bello, taking over the character from Rachel Weisz) and her brother, Jonathan (John Hannah). The two parents are now retired, but they must stop the resurrected tyrannical Han, the Dragon Emperor (Jet Li), a mummy awoken from a 2,000-year-old curse, and whose army was found by 18-year old Alex. The Emperor now wishes to rebuild his empire, and threatens to plunge the world into his merciless, unending service with his Terracotta Army. Their chances of stopping him are thin, for the Emperor has not only an army of great magnitude, but controls the five elements. The undead Terracotta Army faces another, smaller, raised-from-the-dead army made of the Dragon Emperor's enemies, who died when they were crushed under the Great Wall of China. Based on clips of the movie Jet Li's character is able to shape shift into the form of the three headed dragon. The emperor on which this fictitious account was based was Qin Shi Huang and not the first Emperor of the Han Dynasty, Emperor Gaozu of Han.
