#Q ORIGINAL QUESTION

What was the original ending of Double Indemnity?

What a correct answer would look like:

The original ending of Double Indemnity featured Walter Neff's execution in the gas chamber at San Quentin, with Barton Keyes present as a witness. Filmed at a cost of $150,000, the scene depicted the clinical preparations and execution in stark detail. It ended with Keyes, devastated, walking alone down a corridor and into the sunlight. Director Billy Wilder cut the scene before the general release, primarily because he felt the preceding scene in the office—where Neff collapses and Keyes lights his cigarette—provided a stronger emotional climax. The footage is now considered lost, though production stills and the script remain.

What the LLM said (errors and omissions annotated)

The original ending of the 1944 film Double Indemnity, which was filmed but ultimately cut by director Billy Wilder, featured the execution of Walter Neff (Fred MacMurray) in the gas chamber at San Quentin.

In the version of the film we know today, the story ends with a wounded Neff collapsing at the door of the Pacific All-Risk Insurance building after confessing his crimes into a dictaphone, while his mentor Barton Keyes (Edward G. Robinson) lights a cigarette for him and waits for the authorities.

Here are the specific details of the original, deleted "Gas Chamber" sequence:

1. The Setting
The scene moved from the insurance office to the execution chamber at San Quentin State Prison. It was filmed with a stark, documentary-like realism that contrasted with the moody noir shadows of the rest of the film.

2. The Process
The sequence depicted the clinical, grim preparations for a state execution. Walter Neff is shown being led into the chamber by guards. He is strapped into one of the two chairs inside the glass-enclosed room. The camera captures the methodical nature of the guards as they tighten the straps and prepare the cyanide pellets.

3. The Witnesses
Outside the glass, a group of witnesses is gathered. Among them is Barton Keyes. This provided a final, heartbreaking beat for the relationship between the two men. While the rest of the witnesses are stoic or detached, Keyes is visibly shaken and devastated, watching his protégé and friend pay the ultimate price for the crime he uncovered.

4. The Execution
The scene detailed the actual start of the execution. The warden gives the signal, and the lever is pulled, dropping the cyanide pellets into the vat of acid beneath the chair. White gas begins to rise around Neff.

5. The Final Interaction
Before the gas overcomes him, Neff looks through the glass and makes eye contact with Keyes one last time. There is no dialogue, but the exchange acknowledges their bond. After Neff dies, Keyes turns away and exits the observation area, walking slowly down a long corridor.

Why was it changed?
Billy Wilder decided to cut the scene for two primary reasons:

Although the footage of the gas chamber ending is believed to be lost (only production stills and the script remain), it remains one of the most famous "lost" scenes in film noir history.
