Martin Scorcese and Leonardo DiCaprio were recently on the French TV show Le Grand Journal promoting Shutter Island and were asked a question (via video) by actor-director Guillaume Canet that managed to reference a famous Scorcese movie.
A bit of background: Canet worked with DiCaprio on The Beach (2000) and is married to Marion Cotillard, who stars with Leo in the upcoming Christopher Nolan thriller Inception.
