That's the Road to El Dorado
In Spain 1519, two wanted con artists, Miguel (Kenneth Branagh) and Tulio (Kevin Kline), win a map purportedly to the city of gold, El Dorado along with a large number of other valuables by cheating at a game of dice (though the map itself was won fairly). Chased by an angry bull and the city's guards, the two inadvertently hide themselves on the ship belonging to Hernán Cortés and his troops as they set off to the New World. They manage to escape to a rowboat, inadvertently bringing along Cortés' horse, Altivo, and eventually end up ashore on the New World, where Miguel recognizes landmarks shown on the map. The three follow the map and end up where the map marks the entrance to El Dorado, but find only an enscribed monolith waiting for them. As they try to determine what to do next, a young tribal woman is chased by a group of guards, and Miguel and Tulio step in to protect her. The guards believe the two to be gods as shown on the monolith, and escort them along with the woman along a river cavern to El Dorado, truly a city made out of gold.
