Taxi Driver, Raging Bull, Goodfellas, The Aviator and The Departed director Scorsese, 81, whose parents were from villages surrounding Palermo, said he felt “I can unveil something unknown to the audience”.

“[I’m] grateful to Sicily and the Sicilians for the welcome they have given me, once again,” he added.

He said he echoed the sentiments of underwater archaeologist Lisa Briggs, who is helping him with the documentary.

“This project would not have been possible without the incredible help of the Sicilians, and we are moved by these people’s hearts and their welcome.”

Scorsese will be in Turin October 7-8 to pick up an award from the Italian Cinema Museum and give a masterclass.
