Into the Deep (2022)

In 2016, Peter Madsen was in a race to get a rocketship privately built and was also working on a homemade submarine. In 2017, a reporter doing a story on Madsen (Kim Wall) took a ride on his submarine and never returned. Director Emma Sullivan, who thought she was making a doc about an eccentric inventor, wound up in the right place at the right time capturing real-time reactions from those working with Peter and many telling interviews with Peter himself.

The dramatic miniseries "The Investigation" on this same subject was so well-done and fascinating, that I was eager to see this documentary. I do think that watching the series then the documentary is the proper order, but it's compelling and horrible either way.
