If you have AppleTV+, consider Greyhound, about an allied convey across the Atlantic. Tom Hanks.

It is not a light matter. I'm watching for second time. And now I know the story, I think what each of them were feeling the entire time.

It's not literal or documentary. But is different in detail.

@SwiftOnSecurity Consider watching the British film "The Cruel Sea" about the UK and Canadian experience. I knew a few old sailors and it was so realistic they had trouble watching it.
