The Tunnel of Love is a 1958 American romantic comedy film directed by Gene Kelly and starring Doris Day and Richard Widmark. The film follows a married suburban couple who want a child but are unable to conceive. After adopting a child, they find the baby looks suspiciously like the adoptive father (Widmark). It is based on the 1957 hit Broadway play by Peter De Vries and Joseph Fields, which in turn was based on De Vries' 1954 novel. The Tunnel of Love is the first film directed by Kelly in which he did not also appear. Day received a nomination for the Golden Globe Award for Best Actress – Motion Picture Musical or Comedy for her performance.
