What makes a movie cool? Perhaps the better question might be: what is cool? To introduce our list of coolest movies, it seemed like a good idea to start by defining, well, coolness. 

Cool is an attitude of controlled swagger, and cool speaks quietly because it knows it already has your attention. Cool is not afraid. Cool doesn’t have to try. 

Use of the word “cool” to mean hip or avant-garde goes back to jazz and bebop in the 1940s. By 1957, when Miles Davis released his seminal album, “The Birth of the Cool,” the concept had found its footing in the zeitgeist. The new is cool, and so is the original and groundbreaking. Taking risks is the ultimate in cool.

That surely accounts for the inherent, and universally accepted, coolness of the things we see as cool. Jazz and rock are cool — unless they are purposely uncool, as in “This Is Spinal Tap” — and a movie can be cool just because jazz and rock show up in it. Steve McQueen is cool, as are Paul Newman and Audrey Hepburn. Paris and New York are cool, as is Rome. So are Ray Bans, Levi’s, old school sneakers, and vintage Cadillacs. French New Wave director Jean-Luc Godard is cool. And, we are here to say, so are William Powell and Myrna Loy.

Certain periods are objectively cooler than others, which is why the 1960s and ‘70s produced a large number of cool movies. Rebellion and individualism were surging then, and artists sought to push boundary after boundary. Plenty of things were cool, though, throughout the twentieth century.

We recognize that often what makes a movie cool are its groundbreaking special effects, or power to shock. That is a very different kind of cool, the kind that makes one whistle and say, “Coooooool.”

The cool movies below capture freshness, intelligence, rebellion, iconoclasm, individualism, and points of view that inspire the same spirit of independence in us. 

Cool things just make us feel cool too, which is one of the great gifts of watching movies, and the cool never goes out of style. So chill out with these cool flicks, and feel like a hipster... without even trying.

"The Thin Man" (1934)

Director: W.S. Van Dyke

Stars: William Powell, Myrna Loy, Maureen O’Sullivan

Cool Factor: Nick and Nora Charles (Powell and Loy), are stylish masters of cocktails and nonchalance, even while solving tricky murders. Even their dog, Asta, is the coolest of canines.

"The Big Sleep" (1946)

Director: Howard Hawks

Stars: Humphrey Bogart, Lauren Bacall

Cool Factor: Bogart as Raymond Chandler’s hard-boiled LA sleuth, Philip Marlowe. Filled with swift, priceless patter, there are so many plot twists even Chandler was a bit confused. But who cares when you’re having this much fun?

"Rebel Without a Cause" (1955)

Director: Nicholas Ray

Stars: James Dean, Natalie Wood, Sal Mineo

Cool Factor: James Dean as confused teenager Jim Stark delivers the performance that cemented his status as patron saint of youthful rebellion. Natalie Wood, in her first non-child role, is the love interest. That scene at LA’s Griffith Park Observatory: pure magic.

"La Dolce Vita" (1960)

Director: Federico Fellini

Stars: Marcello Mastroianni, Anita Ekberg

Cool Factor: Roma, 1960. Jaded journalist looking for meaning in Rome; finding none. Highlight: Marcello and Anita in the Trevi Fountain, the birth of an iconic image. Cool trivia: “La Dolce Vita” gave us the word “paparazzi.”

"The Hustler" (1961)

Director: Robert Rossen

Stars: Paul Newman, Jackie Gleason, George C. Scott, Piper Laurie

Cool Factor: High stakes, raw hustle, and “Minnesota Fats” (Gleason). Fast Eddie (Newman) puts a human face on winning and losing, while wielding a mean pool cue. This picture singlehandedly revived the game’s popularity.

"Breakfast at Tiffany’s" (1961)

Director: Blake Edwards

Stars: Audrey Hepburn, George Peppard, Patricia Neal, Mickey Rooney

Cool Factor: Audrey in Givenchy, Audrey in a sleep mask, Audrey on a fire escape, Audrey at night, Audrey in the morning. Chic, elusive, Holly Golightly (Hepburn) is the eternal “one who got away.” And just dig that Mancini score.

"Goldfinger" (1964)

Director: Guy Hamilton

Stars: Sean Connery, Honor Blackman

Cool Factor: Prime Bond holds off the plundering of Fort Knox. A perfect spectacle of gold, gadgets, and an Aston Martin DB5. Plus, female foil and best Bond character name, Pussy Galore. And let’s not forget Oddjob’s lethal derby.

"The Graduate" (1967)

Director: Mike Nichols

Stars: Dustin Hoffman, Anne Bancroft, Katherine Ross

Cool Factor: Witty nose-thumbing at convention, a red Fiat barreling towards Berkeley, and that Simon and Garfunkel soundtrack. The opening sequence still communicates the anomie of youth. And “Just One Word: Plastics.”

"Bullitt" (1968)

Director: Peter Yates

Stars: Steve McQueen, Jacqueline Bisset

Cool Factor: McQueen as ruthless cop turns a simple turtleneck with gun holster into high fashion. Did any real detective have a girlfriend as gorgeous as Jackie Bisset? Oh, and the car chase is pretty cool too.

"M*A*S*H" (1970)

Director: Robert Altman

Stars: Donald Sutherland, Elliott Gould, Sally Kellerman, Robert Duvall, Tom Skerritt

Cool Factor: Hawkeye Pierce (Sutherland), Trapper John (Gould), and an omnipresent challenge to military discipline and authority. In this army, suicide is painless, and the anti-heroes are the real leaders. We love you, “Hot Lips”!

"Dirty Harry" (1971)

Director: Don Siegel

Stars: Clint Eastwood, Mae Mercer, Harry Guardino, Andrew Robinson, Smith & Wesson 29 Revolver

Cool Factor: Harry Callahan enters the cool canon via Clint’s rugged individualism and steely way with a (very large) gun. In Callahan, desk-bound bureaucrats meet their match, a new style of rule-breaker is born, and squinting is no longer just for the shortsighted.

"The French Connection" (1971)

Director: William Friedkin

Stars: Gene Hackman, Roy Scheider

Cool Factor: Gritty, authentic New York City locale. Best. Car. Chase. Ever. (With apologies to "Bullitt"). Cops “Popeye” Doyle (Hackman) and Buddy Russo (Scheider) take on the French drug trade, and kick ass.

"American Graffiti" (1973)

Director: George Lucas

Stars: Ron Howard, Richard Dreyfuss, Cindy Williams, Paul Le Mat, MacKenzie Phillips

Cool Factor: Small town angst, T-birds, drive-ins, Wolfman Jack, and a sizzling drag race. And we'll always love Le Mat in a role that inspired the iconic “Fonz” on TV's “Happy Days.”

"Straight No Chaser" (1988)

Director: Charlotte Zwerin

Stars: Thelonious Monk, Jimmy Cleveland

Cool Factor: Rare footage of groundbreaking jazz pianist and ultimate bebop hep cat, Monk, whose brilliant career was cut short by mental illness... but this picture captures him in his prime. Produced by jazz fanatic Clint Eastwood (another cool point).

"Goodfellas" (1990)

Director: Martin Scorsese

Stars: Robert De Niro, Ray Liotta, Joe Pesci, Lorraine Bracco

Cool Factor: Portraying the ultimate in “wiseguy” culture, “Goodfellas” teaches us what it means to be a “made” man. And it ain't all pretty. Pesci steals it as the sadistic Tommy, snagging an Oscar. Marty's really in his element here.

"Trainspotting" (1996)

Director: Danny Boyle

Stars: Ewan McGregor, Jonny Lee Miller, Kelly MacDonald, Robert Carlyle

Cool Factor: Boyle’s stylish interpretation of Irvine Welsh’s novel, set in the seamy drug culture of Edinburgh, explodes onto the screen with Iggy Pop’s electrifying battle cry, “Lust for Life.” Senses astonished, life (somehow) affirmed.

"Run Lola Run" (1998)

Director: Tom Tykwer

Stars: Franke Potente, Moritz Bleibtreu

Cool Factor: Lola, running. She needs to find some money now, or the boyfriend gets in deep trouble. “Run, Lola, Run” is an eighty-one minute rush of adrenaline tempered by the understated connecting phrase, “Und dann.” And then. And how.

"Dogtown and Z-Boys" (2002)

Director: Stacy Peralta

Stars: Sean Penn, Jay Adams, Tony Alva

Cool Factor: This doc traces the history of skateboarding in 1970s Southern California, and is narrated by Sean Penn. Did you see one uncool word in that sentence? Didn’t think so. Innovation is the uncredited star here.

"Lost in Translation" (2003)

Director: Sofia Coppola

Stars: Bill Murray, Scarlett Johansson

Cool Factor: In Coppola’s second feature, underplayed emotions and restrained dialogue are set against the flashy strangeness of contemporary Tokyo. The May-December dynamic never looked so appealing. And Murray can never not be cool, even in hangdog mode.

"American Hustle" (2013)

Director: David O. Russell  

Stars: Christian Bale, Amy Adams, Jennifer Lawrence, Bradley Cooper

Cool Factor: This fact-based, seventies era con involves prime polyester, classic rock, and epic hair. Adams scores as one treacherous lady with (at least) two different sides to her. And Bale’s comb-over is for the ages.
