In most of the Thin Man films, Nick and Nora look like cinema’s ideal couple

“You’re really not like a detective at all,” a fetching dame tells her laid-back interrogator in The Thin Man Goes Home. “You don’t pound the table or shout or threaten.” She’s talking about Nick Charles (William Powell), possibly the most unflappable of big-screen gumshoes, a man whose keen wit is matched only by his stylish nonchalance. Nick drinks like a fish, but never seems truly drunk. He is retired from the sleuthing business, but is always stumbling back into it, as though it were a habit he couldn’t shake or a hobby he couldn’t resist. He does serious work—cracking murder cases, one Sherlockian deduction at a time—with a wink and a shrug. His tongue is always planted firmly in cheek. A stiff cocktail is never far from his grasp. He is motivated mainly by boredom, not always his own.
Though conceived between the covers of a Dashiell Hammett novel, Nick Charles is a creature of classic Hollywood, through and through. He could only exist in a simpler age of crime fiction, before noir corrupted the genre with cynicism. That goes, too, for his heiress spouse, Nora (Myrna Loy), a wealthy socialite whose own taste for adventure is often the catalyst for her husband’s investigations. Not simply condoning his mischief but actively coercing him into it, she’s the refreshing polar opposite of the shrewish-wife archetype. Years into their marriage, Nick and Nora share the sparkling, flirtatious rapport of newlyweds. They also sleep in separate twin beds, as was mandatory for most Code-era cinematic couples. But savvy viewers knew how these doubly besotted lovers spent their downtime, even before they produced an offspring as proof.
Powell and Loy made a whopping 14 films together, six of which belong to the Thin Man series, a franchise reliant less on its murder-mystery mechanics than the profitable dynamic between its leads. (So credible was their chemistry that some of the public mistakenly assumed the actors really were an item.) Like its main characters, the Thin Man movies are fundamentally products of their era: They’re whodunits that double as comedies of manners, presided over by an irreverent private dick who’s always three to four steps ahead of everyone else on-screen—excepting, perhaps, his better half. No matter how grim the material ostensibly grows, tangling an ensemble of suspects in its web of murder, suicide, blackmail, and/or vengeance, the tone rarely skews dark. Each installment ends on an absurdly cheerful note, often with Nick and Nora sharing a celebratory drink with some chipper, non-grieving survivor of the deceased. When things threaten to get too serious, the duo’s troublemaking dog—a fox terrier named Asta—does backflips or runs off with a clue between his teeth.
Many of the franchise’s recurring tropes can be traced back to its first and best entry, 1934’s The Thin Man. Shot over a mere two weeks, on a fairly shoestring budget, the film was conceived by MGM as a B-movie. Director W.S. Van Dyke, who would return to helm three of the five sequels, reportedly fought to cast Powell and Loy, who had appeared together in the previous year’s Manhattan Melodrama (otherwise known as the film John Dillinger watched at Chicago’s Biograph Theater before cops gunned him down). Van Dyke’s casting coup paid off when The Thin Man became a surprise smash, thanks in no small part to its quip-firing stars. Also integral were screenwriters Albert Hackett and Frances Goodrich, a husband-and-wife team who infused the central relationship with an authentically playful, affectionate spirit. (Whether they modeled the film’s marriage on their own is unclear, but there’s no denying Nick and Nora talk like the platonic ideal of evenly matched life partners. There was no one quite like them gracing Hollywood screens at the time—or now, really.)
The thin man of The Thin Man isn’t its detective, but a missing inventor (Edward Ellis) whose Christmas-season disappearance sets the complicated plot into motion. Subsequent entries in the series would nevertheless include the Thin Man moniker, presumably to preserve brand recognition. (It becomes an implied alias for Nick himself, who is admittedly much more svelte than the heavyset gumshoe Hammett described.) Beyond titular influence, this inaugural installment set the template for the whole series, firmly prioritizing whip-smart banter over the accumulation of clues—though there is plenty of the latter. As much as any low-aiming action or horror franchise, the Thin Man movies adhere to a rigid formula. They gave people what they wanted, over and over again, until profit diminished with the returns.
Without fail, Nick’s attempts to just relax and drink away a few afternoons will be disrupted by a sudden murder mystery, practically materializing around him. Reluctantly, and with a big push from Nora, he’ll take the case, outpacing the actual detective investigating (usually an incompetent or overzealous fellow). There will be at least one scene of Nick snooping around where he doesn’t belong, and another of him swearing off the assignment, only to later pretend that his commitment never wavered. There may be a brawl. There will always be a lowlife associate of Nick’s, dropping by to behave uncouthly and raise Nora’s eyebrows. And that mugging canine, a clear comedic ancestor of the Frasier pooch and The Artist’s Uggie, will undoubtedly provide some slapstick assistance—possibly in slow or fast motion. What changes, predominately, is the backdrop: Nick works his magic in New York and San Francisco, Long Island and his New England hometown, on a race track and a gambling boat. Trouble seems to find him wherever he goes, usually on vacation.
Every Thin Man movie ends the exact same way, with a scene of Nick gathering all the suspects at what Futurama’s Dr. Zoidberg would call the “Accusing Parlor.” He talks through the evidence aloud, shakes down potential culprits, and waits for the guilty party to make a critical slip-up. These finales are invariably satisfying: Even when the mystery itself ain’t exactly Edgar Award-worthy—I’m looking your way, later sequels—seeing Nick solve it aloud is what whodunits were made for. Without fail, the accused will cop to his or her crimes, before being tackled to the floor during a pathetic attempt to go out in a blaze of gunfire glory. (No one in a Thin Man movie can shoot for shit, unless they’re aiming at the first victim.) The below scene, from the original, exemplifies this convention, but any and all entries in the series build to a basically identical climax.
