The Family Way (1966)

This overlooked gem of 1960s filmmaking is a beautiful, bittersweet story of newlyweds Hayley Mills (in her first adult role) and Hywel 'Shelley' Bennett who are unable to consummate their marriage because of a cancelled honeymoon and frustrating difficulties caused by too-close-for-comfort in-laws.

Featuring terrific supporting performances by Hayley's real-life father John Mills as her on-screen Dad (the greatest frustrator of all), and the wonderful Marjorie Rhodes.

Best known for its fine, Paul McCartney-penned score, and for Hayley's brief flashes of nudity (and her scandalous off-screen romance with director Roy Boulting, 33 years her senior).
