Cat People(1982)

They are something more than lovers who are about to become something less than human.

After years of separation, Irena Gallier and her minister brother, Paul, reunite in New Orleans. When zoologists capture a wild panther, Irena is drawn to the cat – and zoo curator Oliver to her. Soon, Paul will have to reveal the family secret: that when sexually aroused, they revert into predatory jungle cats.
