69 Years Later, This 100%-Fresh Crime Drama Is Still the Best Agatha Christie Adaptation

For nearly a century, viewers have enjoyed numerous Agatha Christie adaptations – from brilliant performances by David Suchet as Poirot, as well as Hollywood blockbusters from Kenneth Branagh.

However, one movie has remained unrivaled for nearly 70 years. In 1957, Billy Wilder, the genius behind Some Like It Hot, released Witness for the Prosecution, an adaptation of Christie's play of the same name.

What Is 'Witness for the Prosecution' About?

The plot centers on Sir Wilfrid Robarts, a brilliant but gravely ill lawyer whose doctors have forbidden him from taking on criminal cases.

With the help of his caring nurse, Miss Plimsoll, he tries to follow their instructions. However, when his colleague, Mayhew, brings a murder suspect to his home, Robarts can't resist.

Leonard Vole has been accused of killing a wealthy elderly woman who made him the primary heir to her fortune shortly before her death. The motive is obvious and the evidence seems irrefutable, yet Vole himself swears his innocence.

Even After Nearly 70 Years, Billy Wilder's Adaptation Remains Unrivaled

Billy Wilder took Agatha Christie's masterfully twisted play and transformed it into a perfect noir thriller – he heightened the courtroom drama, added noir elements, and kept the central whodunit question open even after the final twist.

The film's crowning glory is Marlene Dietrich as Christine Vole. With an unapproachable demeanor and an icy gaze, Dietrich embodied the classic femme fatale – one whose motives remain elusive until the very end.

Like Robarts, the audience is constantly unsure whose side Dietrich is on, whether she is telling the truth, and if she even has a heart.

'Witness for the Prosecution' Is Humorous, Suspenseful, and Has a Perfect Finale

One of the main reasons Witness for the Prosecution remains the finest Christie adaptation is its remarkable balance of dark tension and sparkling humor.

Charles Laughton's portrayal of Sir Wilfrid is caustic and witty, he possesses an incredible sense of self-importance and is constantly nagging the nurse who hides his cigars. His dialogue with Miss Plimsoll has become a classic and still evokes laughter.

However, it is the finale that sets this film apart from most other detective flicks. Wilder doesn't merely provide us with the answer to the murder mystery – he reveals it with such surprising dramatic force that it literally takes the viewer's breath away.

And after the denouement, the director adds a postscript for those who plan to tell their friends about the ending.
