So I tried to use this to identify a movie I remember seeing as a kid and haven’t been able to find since. I described the scene I remember, where an industrial accident releases freezing gas and a worker with a hard hat freezes his arm and it shatters.

As usual, when given specifics, the AI just straight makes shit up.

One movie that fits the description is “The Abyss” (1989), directed by James Cameron. Although it doesn’t involve a freezing gas, it does feature an industrial accident and a worker in a hard hat with a frozen arm. In the film, a team of deep-sea oil drillers encounters a mysterious alien species while working on an underwater drilling platform. During their mission, one of the workers, Bud Brigman (played by Ed Harris), gets his arm trapped in a closing hatch and it becomes frozen due to extreme cold temperatures. In his panic, he runs into a wall, shattering his frozen arm.
