SPOILERS MAY LIE AHEAD

1. Pulp Fiction - "I'm tryin' real hard to be the shepherd"

Samuel L. Jackson played one of cinema's greatest badasses in 1994's Academy Award winning Pulp Fiction. But after a near-death experience ,the hitman changes his ways. He encounters a thief in a restaurant, and, with a gun in his hand, delivers this line. Jackson lets the thief go. A masterpiece of character growth, writing, and acting.

2. On the Waterfront - "It wasn't him, Charlie, it was you"

One of the most forgotten lines in cinema, as it is overshadowed by "I coulda been a contender". But Terry Malloy, brilliantly played by Marlon Brando, could have been a contender, if only his brother Charlie would have looked out for his younger sibling. This line is one of the most heartbreaking quotes you will find in a movie.

3. The Dark Knight - "I believe whatever doesn't kill you simply makes you...stranger"

This is one of the most memorable entrances to a character in the history of movies. It even barely provides somewhat of a backstory for the Joker, as one can now assume that his scars came from some kind of near-death experience. I love these kind of memorable, iconic lines.

4. Pulp Fiction - "You know what they call a Quarter Pounder with Cheese in Paris? A Royale with Cheese"

I love how this line means almost nothing to the plot, yet it is so meaningful to Pulp Fiction's spirit. The film connects so closely with the viewer's pleasures and interests, so a quote like this
is essential to such a fun film. I love it.

5. Dr. Strangelove - "Gentlemen! You can't fight in here! This is the War Room!"

Not a finer line has ever been written in a comedy than this one. Taking a look at a quote like this proves the point even further that writing good comedy is more difficult than any other genre.

6. This is Spinal Tap - "These go to eleven"

Let's take a look at this one. Rob Reiner is interviewing rock star Christopher Guest about his amplifier. "Most blokes play their guitars at ten" Guest explains, "But our amps are one higher, they go top eleven". Rob Reiner looks a little confused. "Well why don't you make ten the loudest one, but just make it a little louder?" A long pause--Reiner makes a good point. Guest, trying to defend his point, says "These go to eleven".  Brilliant.

7. Raging Bull - "I coulda been a contender"

This scene, if you recall, features an overweight Robert De Niro rehearses his lines in front of his dressing room mirror. He was once a contender, but that life is now long gone. His stand up act is Marlon Brando's speech in the back of the taxi in 1954's On the Waterfront, as their lives are so closely similar.

8. The Godfather - "I'm gonna make him an offer he can't refuse"

A line like this is why we empathize with the Corleone family. The family does not threaten to kill people, they simply make them offers they can not refuse.

9. No Country For Old Men - "Call it"

Possibly the most iconic villain of all time, Anton Chigurh of No Country for Old Men believes in fate; which is why he plays a game of life and death, using this line, with the flip of a quarter.

10. Taxi Driver - "Are you talking to me?"

De Niro just transformed into Travis Bickle in this film. He used this quote at the height of his insanity, standing in front of a mirror.
