A Certain Smile is a 1958 American drama film directed by Jean Negulesco, based on the book of the same name by Françoise Sagan.

Christine Carère was cast in the main role, although she didn't know any English at the time. She was brought to Hollywood and trained for ten months before filming.^[4] The Production Code Administration only authorized the film after substantial changes to the novel's story line. Negulesco later agreed "that A Certain Smile has not much of Sagan. She herself did not like it and she also wrote an article against it. She was right in saying that that was not her book."^[5]
