Fan Casting The Road to El Dorado

In 1519 Spain, two con artists, Miguel and Tulio, win a map to the legendary City of Gold, El Dorado, in a loaded dice gamble (Although this time they win fairly). After their con is exposed, the two evade the guards and hide inside barrels, which are then loaded into one of the ships to be led by conquistador Hernán Cortés for the New World. During the voyage, they are caught as stowaways and imprisoned, but break free and take a rowboat with the help of Cortés' horse, Altivo.
