Lynne Frederick (Lucy) wears the exact same blue Edwardian coat worn by Jenny Agutter two years earlier in Lionel Jeffries' previous film The Railway Children (1970).

This was Laurence Naismith's final feature film appearance before his death on June 5, 1992 at the age of 83.

Bette Davis was first offered the role of Mrs. Wickens, but turned it down out of frustration for being type cast as eccentric and ghoulish older women type of characters.

Hayley Mills was offered the role of Bella. In addition, Helen Mirren was considered for the role.

On one occasion Lynne Frederick had to leave the set half a day early to attend the royal premiere of her film, Henry VIII and His Six Wives (1972).
