Waterworld (1995) is an interesting Sci-Fi movie, but it was never a huge hit in the theaters.
"In 2500,[4] as a result of the sea levels rising over 7,600 metres (24,900 ft), every continent on Earth is now underwater. The remains of human civilization live on rugged, floating communities known as atolls, having long forgotten about living on land. It is believed that a mythological "Dryland" exists somewhere in the endless ocean." https://en.wikipedia.org/wiki/Waterworld#Plot
"It is nicknamed the Mile High City because its official elevation is exactly one mile (5280 feet or 1609.344 meters) above sea level." https://en.wikipedia.org/wiki/Denver

According to the movie, Denver could easily be well under a sea-level of 7,600 metres (24,900 ft).
"Elevation measures the total height above sea level. Whereas, altitude is the height of something over the earth’s surface. Meaning towns, such as Denver, doesn’t have an altitude of 5,280, but an elevation. An airplane going overhead Denver, might be cruising at an altitude of 30,000 feet." https://www.uncovercolorado.com/highest-elevation-towns-in-colorado
As would also be the case for some cities in Mexico, since none of them are at 7,600 metres (24,900 ft).
"Elevations of 5,000 to 7,000 feet above sea level are not unusual for cities in Mexico’s colonial heartland as well as those in the southern states of Oaxaca and Chiapas. Mexico City and Guadalajara are also cities situated at elevation." https://www.mexperience.com/breathing-high-altitudes-in-mexico

Although not directly related to Waterworld, a similar underwater theme is depicted in this music video.
