Thanks, virgomoon. :D
Are we sure, though, that this is about a movie?
I first saw it on the Evening Standard article that had:
For Scorsese aficionados, however, the good news is that Scorsese is reuniting with Robert De Niro for a future project, an autobiographical story "about our lives together", which they will resume writing when De Niro finishes his own directing job, The Good Shepherd, starring Departed star Matt Damon.
De Niro and Scorsese grew up in the same neighbourhood together and the project will look at their experience of the Italian diaspora in America - not a million miles away from the Irish of Boston.
Could it have something to do with that memoir/book they were writing together?
