Overboard (1987)

Joanna, a wealthy and snobbish woman, enjoys a life of pleasure until an accident on her yacht causes her amnesia. Meanwhile, Dean, a widowed carpenter, learns of her accident and decides to take revenge on her, who had been unkind towards him: he makes her believe that she is his wife. When her real husband, Grant, makes his appearance, Joanna is confused, having to choose between two very different lives. A hilarious romantic comedy that capitalizes on the chemistry between Goldie Hawn and Kurt Russell, a real-life couple.
