This is the good documentary I saw (and learned about the story)
The Endurance (2000)
https://www.imdb.com/title/tt0264578/
A retelling of Sir Ernest Shackleton ‘s ill-fated expedition to Antarctica in 1914-1916, featuring new footage of the actual locations and interviews with surviving relatives of key expedition members, plus archived audio interviews with expedition members, and a generous helping of the footage and still photos shot on the expedition.
