Jonathan Tragger meets Sara Thomas by chance in the Christmas eve, in Bloomingdale's, both trying to buy the unique pair of black gloves available for sale. They decide to go to the cafeteria Serendipity and Jonathan asks for her name and phone. Sara decides to write it in a book, and his on a five dollars bill. She gives the bill to a newspaperman and she says that she would sell the book in a New York used books store. She states that if destiny wants them two together, Jonathan will get that book back. Or she will receive that bill again. From this day on, Jonathan will 'chase' Sara's book trying to reach his lost love.

During filming of this movie in NYC, the following note was posted on a production trailer: "Yes, we are filming a movie. It is called 'Serendipity'. It stars John Cusack and some girl from Britain that you wouldn't know - even if we told you her name. We will be shooting tonight until midmorning. Please don't ask the crew any questions. Even if they don't look like they are working, they are thinking."

Lars:
How does Bora Bora sound?


Sara:
Very sexy sexy.

Errors in geography: Dean is an obituary writer for the New York Times. Jonathan asks a cab driver to take him to Dean's office on 42nd Street in Manhattan. The Times' office is on West 43rd Street.
