1. Serpico
   A Beautiful Mind
2. The Hunt
   Bicycle Thieves

In "A Beautiful Mind," the equations that we see on the classroom chalk boards are actual equations that were written by the real life John Nash. After John Nash visited the set, Russel Crowe said he was fascinated by the way John moved his hands and so he tried to do the same thing in the movie. He thought it helped him to better get into character.

1. A Beautiful Mind
   Into the Wild
2. Gone Girl
   The Wolf of Wall Street

For his role in "Into the Wild," Emile Hirsch had to lose 40 pounds to make the weight loss look real. There are no stunt-men or doubles in this entire film. Sean Penn, who wrote and directed the film, waited ten years to make it to make sure the family of Christopher McCandless' was alright with the story being turned into a film.

1. 12 Angry Men
   Oldboy
2. City of God
   Big Fish

"12 Angry Men" is inspired by a real jury duty experience. Reginald Rose, a respected writer for TV at the time, served as a juror in a manslaughter case in 1954. As a dramatist, he wrote "12 Angry Men" as a one-hour teleplay for CBS' Studio One anthology series. It aired on September 20, 1954. This is also the only film that Henry Fonda ever produced.

1. Eyes Wide Shut
   Good Will Hunting
2. Mulholland Dr.
   Little Miss Sunshine

Robin Williams and Matt Damon used to joke around in-character in between takes in "Good Will Hunting," resulting in many of the lines between the two characters being totally improvised. The scene where Matt Damon was in bed with Minnie Driver, he is actually asleep. Because he was producing, writing, and starring in "Good Will Hunting," he was justifiably exhausted.

1. The Pursuit of Happyness
   The Godfather: Part II
2. The Wrestler
   Crash

"The Godfather: Part II," was almost never made. Francis Ford Coppola was exhausted by the time he was done with the original. In later interviews, he said he didn't particularly want to make a sequel because the first part encompassed the entirety of the novel. He ultimately made it because he thought it would be interesting to make two stories in parallel of a man and his father at the same age.

   Gone with the Wind
2. Requiem for a Dream
   JFK

This movie is based on the career of casino boss, Frank 'Lefty' Rosenthal, who is portrayed by Robert De Niro. Director, Martin Scorsese, knew that studios would not want a three hour film, but he ignored them. The film runs for 178 minutes--Scorsese described it as a "fast three hour" movie.

1. Oldboy
   Amadeus
2. Interstellar
   Downfall

Mark Hamill wanted the titular role in "Amadeus," but the director wouldn't let him audition. He thought people wouldn't be able to imagine Hamill as any character other than Luke Skywalker. For the film, Tom Hulce (who was cast in the role instead) practiced piano for four to five hours a day in order to look believable on camera. He also spent a month with a piano teacher before they started filming.

   Malena

During rehearsals for "Scarface," Al Pacino burned his hand on the barrel of a prop machine gun that has just fired 30 rounds; He was out of commission for two weeks.

He saw the classic crime drama at a revival screening in LA and told producer Martin Bregman that he thought he should star in an updated version.

1. Rain Man
   Her
2. The Great Escape
   Inglourious Basterds

On "Oprah", Tom Cruise and Dustin Hoffman said that the "farting in the phone booth" scene was actually improvised as Hoffman actually passed gas while the scene was being filmed. Hoffman said it was his favorite scene ever. Jake Hoffman, the boy at the pancake counter, is Dustin Hoffman's son. Both Jack Nicholson and Robert De Niro turned down the part of Raymond.

2. JFK
   The Wrestler

Although the story of the film, "The Wrestler," does not stray from Robert Siegel's script, all of the backstage locker room scenes (and the first scene where Randy the Ram works a deli counter) were all improvised. In fact, Rourke was serving legitimate customers in that first scene, making his quips to those getting food that much funnier.

1. Goodfellas
   Leon: The Professional
2. On the Waterfront
   Big Fish

The real-life Henry Hill from the movie, "Goodfellas," had too long of a criminal past to fit into a movie. The movie's infamous f-word count was mostly improvised; the script only called for the word to be used 70 times, but much of the dialogue was improvised during shooting, so the expletives piled up. It is actually used closer to 300 times in this film.

1. JFK
   Unforgiven
2. 12 Angry Men
   Goodfellas

Clint Eastwood's production designer, Henry Bumstead, built the main set for the 1880's town of Big Whiskey, Wyoming on a lonesome prairie in Alberta from which no signs of modern civilization could be seen in any direction. The nearest city was Calgary, which was 60 miles away. All of the buildings for the film were fully functional; not just facades.

2. Crash
   The Wrestler

The author of the novel, "One Flew Over the Cuckoo's Nest," never actually saw the film. Although the author, Ken Kesey, was initially involved in the film adaptation of his 1962 novel, he left production after two short weeks and took a lawsuit out against the film's producers. He had multiple grievances against the film, most notably that he wanted Gene Hackman, not Jack Nicholson, to play Randle McMurphy.

1. The Sting
   Gangs of New York
2. La Strada
   Casablanca

The making of "Gangs of New York" took 32 years. It was also shot on a massive set in Rome. Production designer, Dante Ferretti, and his team, built a mile of sets -- stores, saloons, houses, the town square, the harbor, docks and ships -- all of them fully functional, with no facades. People that visited marveled that it was like stepping back in time.

1. Catch Me if You Can
   The Game
2. 21 Grams
   Collateral

According to the real Frank Abagnale Jr., the individual that "Catch Me If You Can" is based upon, approximately 80% of the movie is true. The film shows Frank on the FBI's Most Wanted list, but in real life, he didn't make the list as it is reserved for violent criminals. Another fun fact: To get a sloppy kiss out of Amy Adams, Steven Spielberg told her to pretend she was starving to death and eating a cheeseburger.

1. 12 Years a Slave
   Gone Girl
2. The Social Network
   The Wolf of Wall Street

In "The Social Network," Justin Timberlake, who plays Sean Parker, was the only actor that was able to meet his real-life character.

1. The Truman Show
   Schindler's List
2. Titanic
   Saving Private Ryan

The filming of "The Truman Show" was put on hold for an entire year so that Jim Carrey could finish "Liar Liar."

1. Gran Torino
   The Godfather
2. There Will Be Blood
   A Beautiful Mind

Throughout the filming of "The Godfather," Marlon Brando used cue cards to remember his lines. One of the most famous lines from the movie was actually improvised: it's the line where Peter Clemenza says, "leave the gun, take the cannoli." The horse's head in the film is entirely real.

1. Big Fish
   Zodiac
2. Oldboy
   Birdman or (The Unexpected Virtue of Ignorance)

   The Curious Case of Benjamin Button
2. The King's Speech
   Big Fish

The actual speech, given by the King in the film, is only two-thirds the length of the original. The original speech was 407 words; the movie version only has 269. Four sentences of the speech were deleted, and four sentences were shortened.

1. Braveheart
   Citizen Kane
2. Downfall
   Interstellar

Orson Welles was regarded as one of the great geniuses of his time. Because of this, when making "Citizen Kane," Welles got unprecedented creative control during the film. Welles' original idea for the story was an adaptation of "Heart of Darkness," but ultimately, the idea was nixed because the budget was too high. Instead, it focuses on William Randolph Hearst's life while still tapping into the influence of Joseph Conrad's seminal story.

1. Black Swan
   A Clockwork Orange
2. The Godfather
   The Dark Knight

Stanley Kubrick originally didn't want to make the movie, "A Clockwork Orange." Kubrick didn't like the book upon first reading it because of the Nadsat language Burgess created for the novel. Malcolm McDowell was Kubrick's one and only choice for the role of Alex, and surprisingly McDowell had no idea who Kubrick was. Originally, McDowell thought that the director was Stanley Kramer, the filmmaker behind "It's a Mad, Mad, Mad, Mad World."

   Lost in Translation
2. Léon: The Professional

In "Léon: The Professional," Natalie Portman's parents were against her playing Mathilda, as they thought it was too intense of a role for a pre-teen.

After Portman read the script, though, she says she was moved to tears and knew she had to play the role.

1. There Will Be Blood
   Hotel Rwanda
2. Chinatown
   Bicycle Thieves

The screenwriter for the film, "Hotel Rwanda," spent a year writing the first draft of the script. During the process of writing, he called the Rwandan embassy in D.C.

2. Being John Malkovich
   A Clockwork Orange

Charlie Kaufman, who wrote the script for "Being John Malkovich," said that John Malkovich was the only person that could play the lead actor, although the studio envisioned someone else as the lead role, Tom Cruise.

At first, Malkovich said he wouldn't mind producing or directing the film, but that Kaufman should find a different actor to play him.

1. A Seperation
   The Green Mile

   Argo

The film, "The Green Mile," is based on a novel by Stephen King. He published the book serially, in six installments, in order to follow the example set by Charles Dickens.

2. The Bridge on the River Kwai
   Seven Samurai

"Seven Samurai" was Akira Kurosawa's first Samurai film. At the time "Seven Samurai" entered production, most major Japanese films cost around $70,000.

1. Lawrence of Arabia
   The Pianist
2. American History X

1. The Pianist
   Gladiator
2. No Country for Old Men
   Lost in Translation

"No Country for Old Men" was shot almost entirely in Las Vegas, but Tommy Lee convinced the Coen brothers to film some scenes on location in Texas. Josh Brolin broke his shoulder in a motorcycle accident two days after winning the part of Llewellyn Moss in this film.

   Gran Torino
2. The Big Blue
   The Usual Suspects

In "Gran Torino," Clint Eastwood's son, Scott Eastwood, appeared in the movie as Trey, and his other son, Kyle Eastwood, provided the music for the film.

   Eternal Sunshine of the Spotless Mind
2. Modern Times
   American Gangster

The film, "American Gangster," went through a number of titles, directors and acting duos throughout its development process. It was almost called "Tru Blu" and would have been directed by Brian De Palma or Antoine Fuqua (from "Training Day") and might have alternately have starred Benicio Del Toro and Will Smith in the lead roles. Fun fact: The crowd at Muhammad Ali's fight sequence is made up of 650 extras and 1500 inflatable dummies.

   Amadeus
2. La Strada
   Magnolia

Paul Thomas Anderson wrote the bulk of the script for Magnolia during two weeks he spent at William H. Macy's Vermont cabin.
