Overboard (1987)

A romantic comedy directed by Garry Marshall, starring Goldie Hawn and Kurt Russell.
A poor carpenter is hired by a rich woman who treats him badly. The rich woman falls off her boat and is picked up as an unidentified person. The carpenter then convinces her that she is his wife.
The focus here was on Goldie Hawn's acting. She plays 2 entirely different roles in this film. Plot, characters, blah blah blah... It would have just been o.k., but because of the leading lady's performance, it gets a good review.
