Based on Agatha Christie's successful 1953 play, Witness For The Prosecution benefited from fine tuning from master director Billy Wilder and writing partner Harry Kurnitz. Here the dialogue becomes razor sharp and the characters are fully realised with quite wonderful results, but chiefly the masterstroke here is not letting a court room drama become just that, a court room drama. The film plays out with no wasted scenes, no moments of boredom, and it has such vim and vigour you sometimes forget that there actually is drama in the story.
The cast here are wonderful, Wilder had wanted to work with Charles Laughton for some time, and it's obvious that both parties here are getting the best out of each other. Laughton is a pure delight as Robarts, a sharp tongue, all bluster and cheeky into the bargain, his interplay with Miss Plimsoll (Laughton's real life wife Elsa Lanchester) is quality, and it's another testament to Wilder's genius for putting them together. Tyrone Power, in what would be his last completed film before sadly passing away, is devilishly smart as Vole, whilst Torin Thatcher is great as the gruff prosecution barrister Myers. Yet as good as they all are, they all sit in the shadow of Marlene Dietrich and her turn as Christine Vole, wonderfully sultry and femme fatalistic, it's a sizzling performance that crowns this delightful film.
It occurred to me overnight that it's probably the closest film that Wilder got to being Hitchcockian, and I'm pretty sure the big master of suspense himself would have enjoyed this one. It's a mystery that is dramatic, it's a thriller that is also funny, it's pretty much a multi genre classic. 9/10
