Martin Scorsese has spent many hours of his life watching Robert De Niro act. They've made nine films together since 1973—many of which are regarded as among the greatest of all time. Scorsese helped tease out De Niro's tortured, militant Travis Bickle in Taxi Driver and abusive, decimated boxer Jake LaMotta in Raging Bull. And let's not forget Mean Streets, and Goodfellas, and Casino, so you can be sure that he knows exactly how to mimic the man himself.
