Lucretia (Patricia Medina) is a secondary antagonist in the 1969 Japanese sci-fi film "Latitude Zero".
Lucretia is the wicked mistress of Dr. Malic (Cesar Romero), a scientist of Blood Rock. Dr. Malic wishes to destroy the paradise of Latitude Zero, a paradise hiddent fifteen miles below the surface at the intersection of the Equator and the International Dae Line. Latitude Zero is run by Craig Mackenzie (Joseph Cotten), who captains a submarine known as Alpha. Mackenzie is over 200 years old, and it seems that no one ages or dies at Latitude Zero. In addition, gold and diamonds are common.
Dr. Malic uses giant rats and anthropormorphic bats in addition to James Bond-style devices against the undersea kingdom.
In addition to Lucretia, Dr. Malic has another love interest named Captain Kuroiga (Hikaru Kuroki), who serves him with undivided attention. Captain Kroger is ultimately betrayed when he kills her for punishment for not catching the submarine Alpha. He then grafts the wings of an eagle to a lion, and uses her brain for a transplantation surgery of the same lion.
Lucretia is accidentally killed by Dr. Malic, when the two struggle with her own knife. The blade is thrust into Lucretia's abdomen and she dies.
