Martin Scorsese is going back to his Sicilian roots — he’s set to work on a documentary about shipwrecks off the coast of Sicily that will see him return to Polizzi Generosa, the Italian town where his paternal grandparents were born.

The untitled project, first reported by Italian news agency ANSA, is based off the work of American archeologist Lisa Briggs. The Cranfield University professor specializes in using DNA analysis and other tools on artifacts from shipwrecks to discover new information about the ancient history of maritime trade.
