The Road to El Dorado Sequel

A 2000 Dreamworks film, "The Road to El Dorado" needs to have a sequel. The film is about two con-men (Kevin Kline, Kenneth Branagh) get hold of a map to the lost City of Gold, El Dorado. After stowing away onto one of the ships of the Spanish explorer Cortez, the pair escapes and eventually do find the city. There, a priest (Armand Assante) proclaims them to be gods in a scheme to win control of the city for himself. Meanwhile, they meet a beautiful girl (Rosie Perez) who helps them in their ruse.
The movie ends with the two men and the girl going off into the jungle, and the reason for a needed sequel is that for 1 it was a great movie, and for 2 it left people hanging. Do they ever get back into El Dorado? Do they get off the island? What all happens in their adventure on the island? There is so many questions that need answered, by another great movie.
