You should see the alternate ending on the DVD.
After everything that happens in South America, the movie cuts to Rome. To people are standing over a grave talking.
Person 1: Did you hear what happened?
Person 2: No what?
Person 1: The Jews wiped out the Mayans in Mexico.
Person 2: Those damn Jews...first what happened here...and now the Mayans...if only someone could stand against them.
The two people walk away from the grave and the camera pans down showing whose name is on the grave. It is marked "Jesus." Suddenly a bolt of lightning strikes the grave and:
A hand bursts from the grave. The screen then reads "The End...?"
Alas, the studio thought it was too blatant of a set up for the final film of the trilogy. "Jesus' Revenge."
