What Was Katharine Hepburn's Greatest Movie Ever?

7. On Golden Pond (1981)

Kate won her fourth and final Oscar for this deeply affecting, autumnal swan song about an elderly couple (Hepburn and Henry Fonda) who return to their New England lake house one last time. But their idyll grows turbulent when they are joined by their resentful daughter (Jane Fonda), her new boyfriend and his surly teenage son. On its surface, On Golden Pond is presented as a melodramatic generation-gap drama. But it's elevated to something far richer and more resonant thanks to Fonda's curmudgeon with a soft, chewy center and Hepburn's outwardly fragile but fiercely protective matriarch who does her damnedest to hide her emotions until tragedy brings them to the fore.

Kate's Best Line: “Listen to me, mister. You're my knight in shining armor. Don't you forget it."

6. Little Women (1933)

Hepburn was just 26 when this, the definitive version of Louisa May Alcott's classic novel about the March sisters, hit screens. But the ingenue proved that she was already a formidable talent as Jo. Tracking the fleeting seasonal sorrows and joys of the March girls, the film's vignettes are anchored and fueled by Hepburn's miraculous performance, always aching for something more yet reluctant to let go of the past. Anyone who's seen the movie knows that Hepburn should have been nominated for an Academy Award, but she wasn't. Instead, she got the nod from Oscar that year for the backstage Broadway drama Morning Glory — and won. Right honor, wrong film.

Kate's Best Line: “Aren't we elegant!"

5. Long Day's Journey Into Night (1962)

Playing Mary Tyrone is the female equivalent of tackling Hamlet or Macbeth. It's the Mount Olympus that all great actresses must climb to prove their true greatness. And Hepburn summits this high-altitude challenge with precision, poise and pathos in director Sidney Lumet's remarkable adaptation of Eugene O'Neill's Great American Play. Earning her ninth Oscar nomination for her bravura performance, Hepburn is a bundle of exposed nerves, hopeless dependency and choking claustrophobia opposite Ralph Richardson and Jason Robards in a family tearing itself to pieces. Acting doesn't get much better — and rawer — than this. Its impact is unshakable.

Kate's Best Line: “It makes it so much harder living in this atmosphere of constant suspicion, knowing everyone is spying on me. That none of you believe in me or trust me."

4. Adam's Rib (1949)

This is, hands down, the best of the nine on-screen collaborations between Hepburn and her longtime off-screen partner, Spencer Tracy. It's also the funniest by a mile. Here the two Hollywood legends play married lawyers on opposing sides of a case. He's all world-weary stubble; she's all straight-spined starch. Once again directed by George Cukor, this domestic comedy turns into a slow-simmering battle of the sexes that doesn't go out of its way to make a point but does so anyway. Both leads are perfection. But also keep an eye out for the film's secret weapon, Judy Holliday, as the bubbly blonde on trial for shooting her no good, two-timing husband. A masterpiece.

Kate's Best Line: “Now, you look here, Kip. I'm fighting my prejudices, but it's clear that you're behaving like a … like a … well, I'd hate to put it this way … like a man!"

3. The African Queen (1951)

I suppose one way of looking at this Hall of Fame John Huston adventure-romance is to say it's the closest Katharine Hepburn ever came to making an action movie. Earning her fifth Oscar nomination, here she plays a prim missionary who uncomfortably partners up with a foul-mouthed, gin-drinking boat captain (Humphrey Bogart) to journey downriver one step ahead of invading Germans in the Congo. John Huston's movie deftly mixes treacherous whitewater moments with slower-paced character showcases, where Hepburn's buttoned-up propriety and Bogart's hard-living heathen act produce friction like two sticks rubbing together and making fire.

Kate's Best Line: “I never dreamed that any mere physical experience could be so stimulating!"

2. The Philadelphia Story (1940)

Hepburn picked up her third Oscar nomination for this timelessly daffy love triangle, pitting her like a wishbone between two rival male suitors played by a fuddy-duddy James Stewart (as smitten reporter Macaulay Connor) and a dashing Cary Grant (as her ex, C.K. Dexter Haven). Those names! Whipped into a swoony froth by the great women's director George Cukor, it's easy to see why otherwise sane men would lose their marbles fighting over the hand of Hepburn's Tracy Lord. The Philadelphia Story is a boozy, slapstick-filled tale of upper-class love and honor that hasn't aged a day. If you know someone who has no patience for old black-and-white movies, here's one that will make a convert out of them.

Kate's Best Line: “My, she was yar."

1. Bringing Up Baby (1938)

Arguably the fastest, fizziest comedy from Hollywood's Golden Age of Screwball, Howard Hawks’ madcap, mismatched romance stars Katharine Hepburn as a flibbertigibbet heiress whose pet leopard named Baby leads a bookish paleontologist (Cary Grant) on a wild chase from Manhattan to Connecticut. The live-wire, opposites-attract chemistry between Hepburn and Grant is so electric it may short out the fuse box in your home theater. Grant is great, to be sure, but it's Hepburn who steals every scene with her blue-blood rebel nonconformist streak. Never has she been such a wild wildcard than she is here. Like Grant, you can't help but fall in love with her.

Kate's Best Line: "Mark said that if he wants to wear a negligee, we have to let him wear a negligee."
