Mongol

In the movie, Mongol, the rise to power of Temudjin revolves his love for Borte and his religious devotion.

Temudjin is presented as a combination of Moses, Joseph, and Joshua.

Sandra Hall reviews Mongol as well and finds:

Naturally enough, they're also out to humanise their hero, a job made easier by the decision to deal only with the story of his early life, when he was yet to become acquainted with the character-altering effects of absolute power. They keep it simple. Central to everything is his love for Borte (Khulan Chuluun), his lifelong companion - which, in itself, is enough to make him unique in a society where a man's wife is not nearly as valuable as his horse. He's a 12th-century SNAG in other words, so it hardly seems fair that the Japanese actor Tadanobu Asano (from Takeshi Kitano's Zatoichi) makes him such a stolid personality.

Emphasis Mine

Ghenghis Khan a SNAG! I hate to see a Mongol Rambo, then!

Anyway, back to my religious interpretation of the movie.

Temudjin retraces part of Joseph's journey by being sold into slavery by his blood brother. Whilst in the Tangut prison, he is mocked but a Buddhist monk bargains with Temudjin for the survival of the local monastery. Temudjin agrees if Borte comes. This occurs at the cost of the monk's life.

Instead of the wife having Joseph thrown into prison, the wife releases Temudjin through bribery and threats. And the prophecy concerns the destruction of the Tangut kingdom.

The aspect of Moses' life is that Temudjin is now an escaped slave who was once a nobleman and who had killed one of the slave overseers. He takes his family back into Mongolia. There he goes up to the holy mountain to conceive of the Law for all Mongols (Yassa). The movie only presents three (3) laws.

1. Women and children are to be spared
2. All debts are to be paid
3. Never betray your Khan

Moses got an extra seven. But Temudjin became the Mongol Law Giver. No burning bush or golden calf, though.

In the role of Johusa, Temudjin united the tribes to conquer the Promised Land (Eurasia). Johusa was more modest in his ambitions.

In all cultures, there are the heroic individuals who undergo great trials and betrayals (Joseph), rebel against the existing order to create a new one based on law (Moses), and unite their people in a singular purpose (Joshua).
