1. "Babes in Toyland"
   "Flower Drum Song"
2. "West Side Story"
   "Bye Bye Birdie"

Most of the actors in the Jets and Sharks gangs used their own voices in singing their "West Side Story" tunes. However, the filmmakers didn't use Natalie Wood's own voice; they used a ghost singer for her. Marni Nixon, the one who sang for Audrey Hepburn in "My Fair Lady," sang Wood's songs.

1. "Planet of the Apes"
   "A Clockwork Orange"

   "Wait Until Dark"
2. "Fail Safe"
   "Psycho"

2. "Easy Rider"
   "Cool Hand Luke"

Embodying the true sense of the "free-spirited hippie" movement of the '60s, filmmaker-actors Dennis Hopper and Peter Fonda didn't have a finished script before shooting "Easy Rider." They improvised the material along the way as they went riding from California to Louisiana.

   "The Pink Panther"
2. "Mary Poppins"
   "The Producers"

According to a Merriam-Webster research finding, supercalifragilisticexpialidocious didn't originate with "Mary Poppins" in 1964 because a 1949 song already existed bearing the same title. They also traced an earlier variant in a 1931 newspaper column published by Syracuse University.

1. "Rosemary's Baby"
   "For a Few Dollars More"
2. "True Grit"
   "Breakfast at Tiffany's"

A wannabe socialite singing "Moon River" cemented Holly Golightly as a relatable character in "Breakfast at Tiffany's." Since it's Audrey Hepburn playing it, producers didn't want to get too close to her character's call girl reality, like how Truman Capote wrote it in the book version.

1. "Fahrenheit 451"
   "To Kill A Mockingbird"
2. "A Man for All Seasons"
   "The Prime of Miss Jean Brodie"

1. "Sweet Charity"
   "The Sound of Music"
2. "How to Succeed in Business without Really Trying"
   "Viva Las Vegas"

2. "What Ever Happened to Baby Jane?"

   "The Incident"
2. "Coogan's Bluff"
   "In the Heat of the Night"

"In The Heat of the Night" produced a classic TV and film trope out of Sidney Poitier's classic line: "They call me Mr. Tibbs." As an African American police detective doing an investigation in the south, he had to assert himself with dignity. This line shows how one can command respect.

1. "Bullitt"
   "Bunny Lake is Missing"
2. "The Ipcress File"
   "The Professionals"

Exciting car chase scenes shot on real streets are already common now, but this wasn't the case before the '60s. It took one film to change this stunt landscape: "Bullitt." Having real-life racer Steve McQueen drive as Lt. Bullitt and chase bad guys aboard his Ford Mustang established this trend.

1. "Hello, Dolly"
   "The Fortune Cookie"
2. "Bedazzled"

1. "The Bellboy"
   "The Nutty Professor"
2. "Cactus Flower"
   "Alfie"

Before Michael Caine played the respectable butler Alfred in "The Dark Knight" trilogy, he played the womanizing chauffeur named "Alfie" who called women "it." This shows how expansive the British actor's range can get throughout the decades.

1. "The Unsinkable Molly Brown"
   "The Happy Millionaire"
2. "Scrooge"
   "Chitty Chitty Bang Bang"

Novelist Ian Fleming's knack for naming James Bond characters was also evident in the way he named "Chitty Chitty Bang Bang" characters. Watch the hero Caractacus Potts interact with the lovely Truly Scrumptious and narrate Baron Bomburst's evil deeds in the film adaptation.

1. "The Russians Are Coming, the Russians Are Coming"
   "Dr. Strangelove or: How I Stopped Worrying and Loved the Bomb"
2. "The President's Analyst"
   "One, Two, Three"

Stanley Kubrick served us a Cold War satire with "Dr. Strangelove or: How I Stopped Worrying and Loved the Bomb." One classic quote that sums up this intention goes "Gentlemen, you can't fight in here; this is the war room." Those men were arguing about a doomsday machine and possible war scenarios.

1. "Hang 'Em High"
   "Paint Your Wagon"
2. "The Good, the Bad, and the Ugly"
   "Where Eagles Dare"

It's hard to miss Clint Eastwood's guns and gold-obsessed character termed as The Man with No Name when you see him with a cowboy hat, a small cigar and a poncho. This look appeared in "The Good, the Bad and the Ugly" and in two other works that completed The Dollars Trilogy films by Sergio Leone.

1. "Fantastic Voyage"
   "2001: A Space Odyssey"
2. "Seconds"
   "Barbarella"

If you have an iPhone, try telling Siri to "open the pod bay doors" and you'll get a reply straight out of "2001: A Space Odyssey." Historians note how the movie's A.I. spaceship computer, HAL 9000, influenced tech giants as evident in Apple's A.I. and Amazon's Alexa technology.

1. "The Bridge on the River Kwai"
   "Doctor Zhivago"
2. "The Greatest Story Ever Told"
   "Ryan's Daughter"

It's not ironic anymore to see a Russian-made 2000s TV series of "Doctor Zhivago" since the former USSR can already handle criticism of the Bolshevik Revolution. But in the '50s, Boris Pasternak's book got banned in his own country, and David Lean's '60s film adaptation of it suffered the same fate.

1. "How the West Was Won"
   "Seven Days in May"
2. "Mackenna's Gold"
   "The Sons of Katie Elder"

Seeing films with an impressive ensemble cast is common now, but this was a huge event during Hollywood's early decades. One example of such an event is "How the West Was Won," a Western epic showcasing generations of one family that lived near plains and rivers.

1. "Sunset Boulevard"
   "Monty Python and the Holy Grail"
2. "The Producers"
   "The Little Shop of Horrors"

1. "A Big Hand for the Little Lady"
   "Butch Cassidy and the Sundance Kid"
2. "McLintock!"
   "Cat Ballou"

"Butch Cassidy and the Sundance Kid" is accurate in labeling itself as a loose adaptation of the lives of American who fled to Bolivia in the early 1900s. Books written by Cassidy's descendants and Old West historians contradict facts presented in the film and claim to offer the facts.

1. "Funny Girl"
   "A Star Is Born"
2. "The Way We Were"
   "The Main Event"

It's interesting to note how comedian Fanny Brice got immortalized in two different biographical films: "Funny Girl" and "Can You Ever Forgive Me." The former had Barbra Streisand saying "Well, hello Gorgeous" as she played Brice. The latter starred Melissa McCarthy as Brice biographer Lee Israel.

1. "Zulu"
   "The Dirty Dozen"
2. "In Harm's Way"
   "The Green Berets"

If you think "Suicide Squad" had this unique concept of bringing criminals together to execute a difficult military operation, think again! "The Dirty Dozen" presented this concept back in 1967 about 12 army convicts sent to a D-Day connected suicide mission under Major Reisman's command.

1. "The Manchurian Candidate"
   "The Quiller Memorandum"
2. "From Russia With Love"
   "Thunderball"

If you're wondering why Tony Stark refers to Bucky as "The Manchurian Candidate" in "Captain America: Civil War," that's because the latter suffered a similar fate presented in the '60s film. It's about how a brainwashed soldier gets triggered to commit an assassination by a queen of diamonds card.

1. "El Cid"
   "Cleopatra"
2. "Lawrence of Arabia"
   "Born Free"

Historians say David Lean's epic war film "Lawrence of Arabia" propagated T.E. Lawrence's romantic hero image. This WWI British soldier spent time in the Middle Eastern desert heroically fighting alongside the Arabs. Researchers said this was an inaccurate account of the soldier's real persona.
