Overboard (1987)

In a genre that demands ever more inventive obstacles to its protagonist's ultimate destination, Garry Marshall's Overboard relies on one that may make modern audiences uncomfortable—a rich woman (Goldie Hawn) with amnesia who is duped into believing she is the wife and mother of a guy (Kurt Russell). There's a lot of "positioning" going on to make things more appealing.

Hawn's pre-amnesia character is so dislikeable that her real husband pretends not to recognize her after the accident once he realizes she's lost her memory, and she stiffs Russell's handyman after a job well done—but the plot is ultimately powered by the chemistry and comic timing of its leads, not whether a viewer believes there's a consent problem. This version (as opposed to the 2018 picture starring Anna Farris) it deserves a position on this list simply because Hawn and Russell make it work.
