Adventures in Autographing

Sample Question

I tried looking for this acclaimed actor, director, and restaurateur in the "Mean Streets" of New York, the city he calls home. My "Mission" began in Tribeca, but the film festival he co-founded wasn't running, and he wasn't in any of the restaurants he helped open. I made my way downtown to the Financial District, but the closest I got was a sculpture of a "Raging Bull" charging at a defiant girl. Just as I thought that the story would have to end with "A Bronx Tale", I finally found him masquerading as a "Taxi Driver", of all things! Who is this esteemed thespian?
