The Switch

The film is based on Jeffrey Eugenides' short story "Baster," which was first published in The New Yorker. "The Baster" centers on a neurotic and insecure man (Bateman) who finds out his best friend (Aniston) wants to have a child through artificial insemination. He surreptitiously replaces her donor's semen with his own and is then forced to live with the secret that he is the child's real father.
