Into the Deep: The Submarine Murder Case

In 2016, a young Austrialian filmmaker began documenting amateur inventor Peter Madsen. One year in, Madsen brutally murdered Kim Wall aboard his homemade submarine. An unprecedented revelation of a killer and the journey his young helpers take as they reckon with their own complicity and prepare to testify.

Directed by Emma Sullivan, Into the Deep: The Submarine Murder Case leans on a strong ensemble — Kim Wall, Peter Madsen — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about documentary titles of 2020.
