10 Iconic Movie Moments That Were Completely Improvised

3. Robert De Niro's One Way Argument - Taxi Driver

The films of Martin Scorsese are frequently peppered with memorable lines - indeed, the back and forth between his characters, particularly in his gangster movies, are a trademark of his productions, not least in his collaborative efforts with writer Paul Schrader, who worked with Scorsese on several films including Raging Bull and Taxi Driver. While Schrader undoubtedly deserves a great deal of credit for helping to craft Taxi Driver into the iconic movie of its time, the credit for the most memorable scene in the movie - certainly one of the most quoted in the history of cinema - goes almost entirely to star Robert De Niro. As his character Travis Bickle stands in front of a mirror sizing himself up, the screenplay calls for him to stare menacingly at his reflection. De Niro wasn't satisfied with this, and the now legendary words "You talkin' to me?" were born. Improvisation at its coolest. https://www.youtube.com/watch?v=aVoSt1glAf4
