Into the Deep: The Submarine Murder Case

Into the Deep: The Submarine Murder Case (2020) is a true-crime documentary you can watch online on iFILM. Filmmaker Emma Sullivan started following Danish amateur inventor Peter Madsen long before his name turned up in a murder case.

For more than a year, her camera lived alongside Madsen and the young volunteers who idolized him. Then, aboard the submarine he had built by hand, Swedish journalist Kim Wall was killed. What makes the film so unsettling is its access: footage of a killer before and after the crime, plus the confessions of his helpers as they confront their own complicity and brace to testify. This isn't the news version of the case — it's the view from inside his inner circle. Heavy, claustrophobic viewing for people who watch true crime for the psychology rather than the shock.
