The Amnesia Comedy Tradition Overboard (1987)

Overboard (1987) sits in a genre with a longer pedigree than most viewers realize. The amnesia-comedy is a Hollywood tradition that runs from screwball through wartime through the post-war soap-opera era and into the modern romantic comedy, and Overboard is one of its most structurally clean examples — a film that uses amnesia not as a plot complication but as the device that demonstrates an argument about identity.

Amnesia entered the comedy tradition through the screwball era

Hollywood's first wave of amnesia plots came in the late 1930s and early 1940s, partly through screwball comedies (I Love You Again, 1940, with William Powell as a cheap crook who becomes a respectable Pennsylvania businessman after a head injury) and partly through wartime melodramas (Random Harvest, 1942, with Ronald Colman as a shell-shocked WWI veteran who marries a chorus girl, recovers his pre-war memory and station, and forgets her). The two films establish the genre's poles: amnesia as comic identity-swap (the screwball pole), or amnesia as melodramatic identity-loss (the soap pole).

"The amnesia plot is one of Hollywood's oldest reliable engines. You change one fact about a character — they don't know who they are — and you can put them anywhere, do anything to them, and the audience will follow because the audience knows more than the character does." — David Bordwell, Observations on Film Art (2014)

The genre's structural appeal is the dramatic-irony economy: the audience knows what the protagonist does not (or, in the case of conscious con jobs, the secondary character knows what the protagonist does not), and the entire dramatic apparatus runs on the asymmetry until the memory returns.

The 1940s consolidated the conventions

Through the 1940s the amnesia-comedy and amnesia-melodrama overlapped in a stack of films that treated the device as both joke and engine: Spellbound (1945, Hitchcock), Mister Buddwing (1966), The Major and the Minor (1942, Billy Wilder, with adjacent identity-swap rather than amnesia), and the Bob Hope vehicles that played with the device in deliberately silly registers.

The convention these films established and that Overboard inherits: amnesia produces a new protagonist who is not the same person the audience met at the start, and the film's third act is the negotiation between the new protagonist and the returning original. The amnesia is never permanent — the genre requires the memory to come back so that the negotiation can occur — and the question the film is always asking is whether the new self has built anything worth keeping.

Overboard is the screwball-pole answer to that question

Overboard's answer to the genre's central question — "is the new self worth keeping?" — is unambiguously yes. The film's structural argument (see Themes and Analysis (Overboard) and Plot Structure (Overboard)) is that the practiced self is morally and developmentally a step up from the inherited self, and that the protagonist's job after the memory returns is to choose the practiced one. This is the screwball-pole answer; the soap-pole answer (as in Random Harvest) is that the inherited self always wins and the new self is the casualty.

The two-paths reasoning in two-paths/two-paths-reasoning-overboard addresses the device explicitly:

"The amnesia is the device the film uses to strip the inherited beliefs and let her find out what she does when she doesn't already know what she 'is.' ... You don't need to wipe a mind to teach someone different goals or different techniques. You need to wipe a mind to demonstrate that station is not the kind of thing memory holds."

This is the structural reading that explains why Overboard is in the tradition rather than incidentally borrowing from it. The amnesia in Overboard is not a plot complication that happens to be available; it is the device the film requires to make the argument it is making.

The 1980s brought a small wave

Amnesia-comedies were unfashionable through the 1970s and recovered in the 1980s alongside the broader high-concept-comedy boom. Overboard (1987) is the most-remembered of the cycle, but the period also produced:

• Desperately Seeking Susan (1985) — adjacent identity-swap rather than full amnesia, but plays with the same dramatic-irony economy
• Big (1988) — body-swap rather than amnesia, but uses the same "protagonist learns who they are by being someone else" engine
• Regarding Henry (1991) — the soap-pole answer: a high-powered lawyer is shot in the head, loses his memory, and becomes a kinder person; the film is built around the wife's recognition that the new husband is the man she wishes she had married
• Total Recall (1990) — Schwarzenegger sci-fi action treatment, with the amnesia as memory-implant; the genre had become flexible enough to support the action-thriller register

The genre's most thoughtful 1990s entry is Christopher Nolan's Memento (2000) — anterograde amnesia rather than retrograde, art-film rather than comedy, but built on the same recognition that identity-without-memory is the question the device exists to ask.

The Hawn–Russell pairing was structurally innovative

What Overboard did within the tradition that earlier amnesia-comedies had not done was put the amnesia at the center of a romantic-comedy structure where the love interest is also the perpetrator of the deception. The 1940s amnesia comedies usually paired the amnesiac with a sympathetic outsider (a doctor, a stranger, a found family) and let the audience root straightforwardly for the relationship. Overboard makes the love interest the con artist — Dean is the man who claimed Joanna at the hospital under false pretenses for revenge — and the film's structural challenge is to bring the audience around to the relationship despite that origin.

The way the film does it is by separating the silent commitment (Joanna at the dish sink, after the breakdown, with no announcement) from the held confession (Dean trying to tell her at b27 and being pre-empted at b29). The audience watches Dean want to tell the truth and lose the chance, repeatedly, while Joanna builds a self inside the lie that she will not want disturbed when the truth arrives. By the time Grant arrives in the front room at b31–b32 and the memory return happens, the audience has been positioned to want both the lie's exposure (because Dean deserves the relief) and the practiced self's survival (because Joanna deserves to keep what she has built). That is structurally innovative within the tradition.

The 2018 remake worked the genre conventions in reverse

The 2018 Overboard remake (directed by Rob Greenberg, starring Anna Faris and Eugenio Derbez) reversed the gender of the lead and the amnesiac: a working-class Latina cleaner kidnaps an amnesiac Mexican playboy and conscripts him into a working-class life. The reversal makes the genre conventions visible by using them backwards. See The 2018 Remake for the full discussion.

Where the tradition went after Overboard

Amnesia-comedy has continued as a recognizable Hollywood register: 50 First Dates (2004, anterograde amnesia romantic comedy with Adam Sandler and Drew Barrymore), The Vow (2012, Channing Tatum and Rachel McAdams, the modern dramatic version), Long Shot (2019, with adjacent identity-swap rather than amnesia). Overboard itself is the version most-remembered as the screwball-pole reference; when modern romantic comedies want to invoke the tradition, Overboard is the title they invoke.

"Every amnesia romantic comedy made since 1987 has been measured against Overboard. It is the version that works." — A.O. Scott, The New York Times (2018, Overboard remake review)
