Latitude Zero

Latitude Zero (緯度ゼロ, Ido zero) is a 1969 tokusatsu film created by Toho Company Ltd.

Plot Synopsis
After Dr. Ken Tashiro, Dr. Jules Masson, and Perry Lawton get trapped in a bathysphere due to seismic activity, they are rescued by the crew of the Alpha, a supersubmarine that was launched in the early 19th century. They are greeted by the ship's captain, McKenzie whom they learn is over 200 years old. McKenzie takes the men to Latitude Zero, an underground paradise located at the intersection of the Equator and the International Date Line.

In Latitude Zero, gold and diamonds are plentiful, the inhabitants are peaceful, nobody ages or dies, and everyone lives in peace and harmony. But, McKenzie's rival Dr. Malik (who is also over 200 years old) doesn't feel the same way as Latitude Zero's inhabitants. Malik wishes to destroy it using everything he can conjure.

Of all the visitors to Latitude Zero, only one named Perry Lawton, a journalist, wished to return home. He was picked up by a US Navy vessel and is left with Cmdr. Glenn McKenzie and Lt. Hastings. Consfused at why the people he had previously seen had different names and why the two mortal enemies were acting so friendly toward each other, Lawton discovers his film is ruined and when he opens the pouch where he placed his complimentary diamonds, he finds tobacco. Just as he is about to resign himself to the fact that his adventure never occurred, the ship is wired a message stating that a cache of diamonds has been deposited in his name in a safe deposit box in New York City.
