The 2010 romantic comedy The Switch is a feature-length adaptation of Jeffrey Eugenides' short story "Baster," which originally appeared in The New Yorker in 1996. The film retains the core premise: single woman Kassie (Jennifer Aniston) decides to have a baby via artificial insemination, and her neurotic best friend Wally (Jason Bateman) accidentally swaps his own sample for the donor's. The movie expands the story into a full romantic comedy, adding a seven-year time jump and a meet-cute dynamic between the lead characters.
While the short story ends on a more ambiguous and unsettling note, The Switch adopts a conventional Hollywood ending, with Kassie and Wally ultimately falling in love. The film was initially developed under the title The Baster before being renamed to avoid controversy. Directed by Will Speck and Josh Gordon, the movie received mixed reviews but was noted for the chemistry between its leads and its surprisingly heartfelt take on unconventional parenthood. It stands as a rare example of Eugenides' work being adapted for the screen, with his signature wit and emotional complexity somewhat smoothed over for mainstream audiences.
"Baster" is a short story by American author Jeffrey Eugenides, first published in the August 5, 1996 issue of The New Yorker. The story explores themes of fertility, friendship, and the complexities of modern relationships through a darkly comic premise. Its central conflict arises when a single woman, Kassie, decides to have a child via artificial insemination using a sperm donor, and her longtime best friend, Wally, secretly substitutes his own sperm for the donor's sample.
Eugenides, who later won a Pulitzer Prize for his novel Middlesex, wrote "Baster" during a period when his short fiction was gaining recognition. The story is characteristic of his work in its blend of sharp observation, emotional depth, and unexpected twists. It sparked discussions about reproductive choice and male friendship, and its titleβa play on the word "bastard"βreflects the story's wry tone. "Baster" remains one of Eugenides's most frequently anthologized short stories and has been praised for its tight construction and psychological insight.
