Agatha (1979)

In 1926, writer Agatha Christie disappeared for 11 days and it remains a mystery what actually happened during that time. This film imagines a history where she has followed her husband’s lover to a spa in Harrogate. Vanessa Redgrave portrays Christie appealingly, but the film turns out somewhat as a lackluster mystery. This isn’t helped by the inclusion of American reporter Dustin Hoffman who is offered as an uninteresting love interest.

Oscar Nomination: Best Costume Design
