Witness for the Prosecution: Review, Cast, and Best Version

Marlene Dietrich spends most of Witness for the Prosecution sitting perfectly still in a London courtroom, watching her husband’s murder trial with an unreadable face — a stillness that powers one of cinema’s most famous twists in a film now seen as a milestone of the courtroom drama genre. This guide weighs Billy Wilder’s 1957 classic against the BBC’s 2016 retelling and answers viewer questions about cast, runtime, and the identity of the murderer.

Director: Billy Wilder · Original Release: 1957 · Runtime: 116 minutes · Academy Award Nominations: 6 · Based on: Agatha Christie short story · Starring: Charles Laughton, Marlene Dietrich, Tyrone Power

Six rows tell the essential story: the film’s specs are consistent across major references, even if a few runtime listings drift by a couple of minutes.

Is Witness for the Prosecution a good film?

Short answer: yes. The critical and audience signals line up in a way that is rare for a six-decade-old courtroom picture.

Critical reception

• Rotten Tomatoes (review aggregator) gives the film a perfect 100% approval score (Rotten Tomatoes (review aggregator)).
• Encyclopaedia Britannica classifies the film as a courtroom drama built around Billy Wilder’s direction.

A clean critical sweep plus a reference-work classification puts the film in rare company. Few courtroom stories, Christie’s or otherwise, have aged with this much authority.

Audience reviews

• IMDb (film database) user reviews consistently describe the film as a classic, with ratings that keep it among the top courtroom dramas on the platform.

The audience signal matters because courtroom dramas usually date badly. Wilder’s staging still works, and new viewers keep finding it.

Awards and nominations

• The film earned six Academy Award nominations but won none (Encyclopaedia Britannica (reference publisher)).

What this means: the missing win matters less than the tally. Oscars age poorly; this film hasn’t.

Which version of Witness for the Prosecution is best?

For most viewers, the 1957 film is the definitive version; the 2016 BBC miniseries is the strongest alternative for anyone who prefers modern TV pacing.

1957 film vs 2016 BBC adaptation

• 1957: a single theatrical feature directed by Billy Wilder.
• 2016: a two-part BBC television miniseries; the Apple TV (streaming catalog) listing credits Andrea Riseborough, Kim Cattrall, and Billy Howle in the principal roles.

The format difference shapes everything: one version is a 116-minute theatrical night; the other is a two-episode event built for television.

Key differences in plot and cast

• 1957 cast: Tyrone Power as Leonard Vole and Marlene Dietrich as Christine (IMDb (film database)).
• 2016 cast: Andrea Riseborough, Kim Cattrall, and Billy Howle lead, per the Apple TV catalog listing.

The casting alone signals a different approach: Wilder leans on Hollywood glamour, while the BBC production leans on prestige-TV naturalism.

Viewer reception comparison

• The 1957 film holds a 100% score on Rotten Tomatoes (review aggregator).

The 2016 version hasn’t been around long enough to build the same kind of cross-generational consensus. Television premieres simply don’t accumulate aggregate scores the way theatrical releases do.

The trade-off: the 1957 version wins on reputation; the 2016 version wins on accessibility for modern viewers.

The implication: for viewers who value critical consensus, the 1957 film is the safe choice; for those who prefer modern television pacing, the BBC version is a worthy alternative.

How long is a Witness for the Prosecution on for?

Theatrical runtime

• Encyclopaedia Britannica (reference publisher) lists the 1957 film at 116 minutes (Encyclopaedia Britannica (reference publisher)).
• IMDb (film database) lists 1 hour 56 minutes — the same runtime expressed differently (IMDb (film database)).
• Rotten Tomatoes (review aggregator) shows 114 minutes, a two-minute discrepancy that appears in some listings (Rotten Tomatoes (review aggregator)).

The practical lesson: the original is a tight two-hour sitting, not a three-hour epic. The variation between 114 and 116 minutes won’t change your evening.

TV miniseries runtime

• Apple TV (streaming catalog) lists the 2016 BBC adaptation at 1 hour 57 minutes (Apple TV (streaming catalog)).

Because it was structured in two parts, the miniseries runtime sits just under two hours when watched without commercial breaks.

The catch: both versions fit a standard two-hour window, so runtime is trivia, not a dealbreaker.

Who played the woman with the letters in Witness for the Prosecution?

Character background

• Marlene Dietrich plays Christine Vole, wife of the accused Leonard Vole, in the 1957 film.
• The “woman with the letters” is the trial’s pivot: her letters seem to connect Leonard Vole to the murder and set the courtroom drama in motion.

In the 1957 version, Christine is the character viewers watch most closely — the letters only matter because of how she reacts to them.

Actress Marlene Dietrich’s performance

• Dietrich was 55 when she played the part, according to the film’s page on Wikipedia (community encyclopedia) (Wikipedia (community encyclopedia)).

Dietrich’s performance turns the courtroom into a staring contest. She delivers most of her best work without moving; the restraint is what makes the ending land.

Why this matters: Dietrich’s stillness is the film’s secret weapon — the letters plot only works because the audience can’t read her face.

Who was the real killer in Witness for the Prosecution?

Spoiler alert: The twist revealed

• The twist, preserved in every major adaptation, is that Christine Vole is the real killer.
• She murders the wealthy widow to frame her husband, then confesses in the story’s final act.

That reveal is why the film’s title works on two levels: Christine is the prosecution’s witness, but she’s also the story’s hidden author.

How the murder was planned

• The letters are the mechanism — they make Leonard’s guilt look airtight so the courtroom reversal can land with maximum force.

The cleverness is in the double audience: the jury in the film is convinced, and so is the audience in the theater.

The catch: the twist only works once. That’s why the 1957 film is best seen before anyone summarizes it — knowing the ending rewires the whole movie.

How old was Marlene Dietrich when she did Witness for the Prosecution?

Marlene Dietrich’s age at filming

• As covered above, Dietrich was 55 during filming — a rarity for a female-led role in 1950s Hollywood.
• Born in 1901, she was already a star for nearly three decades by the time she played Christine.

The age detail matters because Hollywood rarely gave women in their mid-50s this kind of screen-dominating role, especially in the 1950s.

The biographical questions nobody agrees on

• The exact number of Dietrich’s lovers is not documented in any reliable public source; biographies describe relationships with figures including Gary Cooper.
• Dietrich’s daughter Maria Riva wrote a memoir that describes a complicated family relationship, not a simple verdict on whether she was “nice.”
• Ernest Hemingway, a close friend, called her a fascinating woman.

The trade-off: “nice” was never really the category. Dietrich built her screen persona on glamour and control, and the people closest to her saw both the cost and the power of that control.

Set the two versions side by side and one pattern emerges: same story, very different grammar.

For most viewers the decision isn’t which version is “better” — it’s which version to watch first.

Two voices capture why this story keeps being remade.

Witness for the Prosecution has stayed alive for so long because its twist isn’t really the point — the point is watching a master observer realize she’s been outplayed. The 1957 film and the 2016 BBC miniseries approach that moment from different directions, and each rewards a different kind of viewer. For first-time viewers, the choice is clear: watch the 1957 original before anyone spoils it, or accept that the twist will land with half the force it deserves.
