As any fan of Martin Scorsese knows, he isn't afraid to take dangers and take full benefit of any moment of spontaneity or surprise. Throughout his long and glorious career as a filmmaker, (source) he is been identified to ask improvisation into his scenes and (source) sometimes occasions the result's one thing really memorable. Listed here are my top 10 favorite improvised scenes from Martin Scorsese motion pictures.

1. "Mean Streets" (1973): At the end of this violent and typically darkly comic gangster flick, (source) Harvey Keitel and Robert De Niro find themselves in a tense stand-off throughout a crucial moment in the movie. De Niro pulls out his gun and improvises a line to Keitel that is really chilling: "You don't f--king know me."

2. "Taxi Driver" (1976): This traditional scene between Travis Bickle (De Niro) and Betsey (Cybill Shepherd) includes a classic misunderstanding between the two characters that lasts for about two minutes. Bickle interrupts the dialog with another improvised line: "You talkin' to me?" It's a legendary second in movie history.

3. "Raging Bull" (1980): On the opening of the movie, Jake LaMotta (De Niro) goes on a memorable rant about his boxing career and especially his rivalry with Sugar Ray Robinson. Every time LaMotta gets worked up, he unleashes a real verbal assault, with extremely improvised words.

4. "The King of Comedy" (1982): The grasp of improvisation, De Niro, steals the present as wannabe comic Rupert Pupkin. In the course of the climactic scene, Pupkin starts to improvise a few of his cleverly crafted comedic material. It's certainly one of De Niro's funniest scenes ever.

5. "After Hours" (1985): Just because the plot of this film gets crazier and crazier, De Niro seems in a tiny position as a current criminal who is attempting to get one over on the protagonist. De Niro goes on a heated, impulsive rant that's so entertaining you almost forget he is a criminal.

6. "The Color of money" (1986): In an intense bar scene between Tom Cruise and Paul Newman, their dialogue begins off as a traditional Western-fashion, testosterone-crammed "mano a mano" change. But when Newman decides to improvise a scene, he takes the conversation in an attention-grabbing path and the result's a basic.

7. "Goodfellas" (1990): This movie is certainly one of Scorsese's best achievements and contained some of his most intense and improvised scenes. During a scene in a restaurant, Joe Pesci, Donnie Brasco, and Ray Liotta all flip their dialog into a three-manner road fight of sharp-witted dialogue.

8. "The Age of Innocence" (1993): On this beautiful movie, Daniel Day-Lewis and Michelle Pfeiffer turn a traditional dialog into something special. They begin to flirt and their phrases turn out to be almost like a dance. Both actors improvise in this scene, with Day-Lewis taking the lead in the improvisation.

9. "Casino" (1995): In a tense scene between Sharon Stone's character and her husband (De Niro), he improvises a memorable line that is now part of movie lore. Stone begins to talk again and De Niro thinks of a line on the spot: "I'm sorry, after all I wasn't talking to you." Brilliant.

10. "The Wolf of Wall Street" (2013): In one of the funniest scenes on this loopy movie about excess, Leonardo DiCaprio's character stays within the office all night and starts to improvise a gross sales pitch for a ketchup bottle. It is a scene that's so full of power and unexpected surprises that it virtually feels improvised off the highest of DiCaprio's head.

Whether it's because of the genius of Scorsese, the improvisational expertise of his forged or a mixture of both, these moments are an integral part of why these films are so beloved. Long live improvisation in film!
