WITNESS FOR THE PROSECUTION: Billy Wilder Film Study
Billy Wilder was known for his reverence for the structure of a screenplay, and subsequently, it influenced his films. In particular, he preferred that all screenplays and films be constructed in a three chapter format like a good play. Agatha Christie’s WITNESS FOR THE PROSECUTION was an international success on stage, and being tossed around as a possible film adaptation by producer Arthur Hornblow, Jr. The producers approached Marlene Dietrich to play the iconic role of Christine Vole (Vivian Leigh was also considered). Her only condition was that her friend, Billy Wilder, direct.

She was even more of a crowd-cheering delight than you could even imagine- with all the Hollywood glamour and effervescent energy decades younger than her eighty-five years.)
Billy Wilder’s WITNESS FOR THE PROSECUTION is essentially the same courtroom drama as Agatha Christie created, but Wilder enhanced the plot by playing up an extended focus on key characters. This was especially true for the witty banter between Elsa Lanchester’s nurse Plimsoll and Charles Laughton’s Sir Wilfrid. I don’t know what the Hollywood obsession is with fawning over cantankerous, obstinate men, but the formula has worked well. The two actors were married in real life, in a marriage of mutual convenience as Laughton was gay and Lanchester had more ambitions for a career than for a traditional family dynamic. It was said that both Marlene Dietrich and Charles Laughton had a crush on Tyrone Power.

Elsa Lanchester, Charles Laughton on the French Riviera- the couple were married (of convenience) in real life.

Both Dietrich and Laughton had crushes on Tyrone Power- can we blame them?
The film starts with barrister Sir Wilfrid Robarts (Laughton) coming back home after several weeks of recovery from a heart attack. His doctors’ orders are to avoid stress; no murder trials especially. And yet, that’s exactly what he does. His new client, Leonard Vole (Tyrone Power) challenges his curious mind through a maze of challenges of incriminating evidence, including a surprising show of loyalty from his wife, Christine (Marlene Dietrich).
There were concerns that Power looked older than his part due to years of alcoholism. In an odd twist of fate, even though it’s Laughton’s character that is constantly under a microscope for a bad ticker, Tyrone Power is the one who (in real life) succumbed to a heart attack during filming of his very next film, SOLOMON AND SHEBA (1959). As such, he was unable to complete that film, and Yul Brenner was brought in to complete. WITNESS FOR THE PROSECUTION (1957) was also the last motion picture feature for Una O’Connor. Her role provides comic relief, thanks to the enhanced dialogue.
Billy Wilder enjoyed working with both Marlene Dietrich and Charles Laughton, admiring their professionalism greatly. From “Conversations with Wilder,” Wilder chatted about this in detail with Cameron Crowe…
BW: “Laughton was everything that you can dream of, times ten. We would stop shooting at six o’clock, and we would go up to my office and would be preparing for next day’s shooting. There were twenty versions of the way he could do a scene, and I would say, “ That’s it! All right!” And then the next day, on the set, he comes and he says, “I thought of something else.” And that was version number twenty-one. Better and better all the time. He was a tremendous presence. Tremendous presence, and a wonderful instrument, wonderful vocal instrument. When he spoke to the audience, they were very quiet. Because they knew. He did not just speak. He said something. And the sum total of it was a great performance. He only got one (Academy) Award, for THE PRIVATE LIFE OF HENRY the VIII (1933). But he was an absolute marvel.”
Secrecy is a critical element to the success of this film. Not unlike how Alfred Hitchcock handling of PSYCHO, the audience is firmly instructed to not reveal the climatic ending. Even the cast and crew were sworn to secrecy with the last 10 pages of the script saved until the final day of shooting.

Prepping the set

As for the Hitchcockian feel of this film, Alfred Hitchcock said, “Many times, people have told me how much they enjoyed WITNESS FOR THE PROSECUTION (1957). They thought it was my film instead of Billy Wilder’s. And Wilder told me people asked him about THE PARADINE CASE (1947), thinking he had done it.”
It was well-received by critics, fans, and at the box office. Even Agatha Christie herself said at the time that it was the only film adapted from one of her stories that she actually liked. (Later, she also enjoyed the Sidney Lumet version of MURDER ON THE ORIENT EXPRESS (1974).) While WITNESS FOR THE PROSECUTION was nominated for several awards, including 6 Oscars (including Best Picture nom), Marlene Dietrich was not one of them. She was so confident that she would be an Academy Award nominee, however, that she prepared the news to be included in her Las Vegas show opener. Alas, that never came to fruition.
One more tidbit that I found of personal interest (and yes, spoilers abound). Ageism is a running theme in this story- with the challenge of aging actors behind the scenes. We see Tyrone Power as Leonard Vole, portrayed as the gold digger wooing Emily French (Norma Varden), depicted as the older widow of means. Furthermore, we are led to believe Dietrich as his war bride is somewhat more age appropriate to him than, say, a 22 year-old Ruta Lee. The 43 year old actor Tyrone Power’s aging reflected his ill health, but his charm and good looks persuade us to not believe our own eyes. Meanwhile, Dietrich’s master skills in camera lighting and makeup make us believe that there was a much wider age gap between Christine Vole and Emily French than in reality. (Dietrich was 56 years old and Norma Varden was 59 at the time of this film’s release.) I may chalk this up to yet another case for women actors being forced to play either much younger roles, (with the enhancement of makeup, lighting, and plastic surgery) or spinsters in their 40s and 50s. Despite the hodgepodge of ages, we are pulled into the superb performances and timeless storytelling for a classic courtroom drama of suspense that continues to captivate.
