Nick Hornby knew better, but he didn’t care. Because suddenly there was that face—the upturned nose, the lupine grin, the wary expression barely softened by the passage of, what, three decades now? Everyone else in the London club that December night was flittering around Colin Firth, set aglow by the Oscar buzz for his performance in The King’s Speech. Hornby let them flit. For here stood … Kevin Bacon. Undisturbed. That knowing smirk may have derailed him as a leading man, but it has allowed for a career of darker, richer roles—and allows him still to cruise a cocktail party longer than most boldfaced names without some fanboy rushing up to say how wonderful he is.

God knows, Hornby had seen that too often: an actor friend, eyes darting, cornered by a gushing stranger. This belated celebration of Firth’s 50th birthday was a private bash where artists and actors, people like Firth and Bacon—and, well, Hornby—could expect to relax. After all, between best-selling books such as About a Boy and a 2010 Academy Award nod earlier in the year for his screenplay for An Education, he had been cornered plenty himself.

Yet when he saw Bacon, Hornby couldn’t help it. He edged closer. It was like that scene from Diner when Bacon’s buddy sees a boyhood enemy in a crowd and breaks his nose: Hornby had no choice. In 1983 a girlfriend had brought home a tape of director Barry Levinson’s pitch-perfect comedy about twentysomething men, their nocturnal ramblings in 1959 Baltimore, their confused stumble to adulthood. Hornby was 26, a soccer fanatic, a writer searching for a subject. Diner dissected the male animal’s squirrelly devotion to sports, movies, music, and gambling. Diner had one man give his fiancée a football-trivia test and had another stick his penis through the bottom of a popcorn box. Hornby declared it, then and there, “a work of great genius.”

Midway through the movie, the ladies’ man Boogie, played by Mickey Rourke, is driving in the Maryland countryside with Bacon’s character, the perpetually tipsy Fenwick. They see a beautiful woman riding a horse. Boogie waves the woman down.

“What’s your name?,” Boogie asks.

“Jane Chisholm—as in the Chisholm Trail,” she says, and rides off.

Rourke throws up his hands and utters the words that Hornby, to this day, uses as an all-purpose response to life’s absurdities: “What fuckin’ Chisholm Trail?” And Fenwick responds with the line that, for Diner-lovers, best captures male befuddlement over women and the world: “You ever get the feeling there’s something going on that we don’t know about?”

In all, the scene encompasses only 13 lines of dialogue—an eternity if you’re Bacon at a party and a stranger knows them all. But Hornby wouldn’t be stopped. “I pinned that guy to the wall, and I quoted line after line,” Hornby recalls. “I thought, I don’t care. I’m never going to meet Kevin Bacon again. I need to get ‘What fuckin’ Chisholm Trail?’ off my chest.”

The Invention of Nothing

Hornby could not have planned a more apt tribute: Diner introduced to movies a character who compulsively recites lines from his favorite movie—and nothing else. And Hornby’s subsequent books about a fan obsessed with Arsenal football (Fever Pitch) and another obsessed with pop music (High Fidelity)—two postmodern London slackers who could easily have slid into a booth at the Fells Point Diner—are only the most obvious branches of the movie’s family tree.

Made for $5 million and first released in March 1982, Diner earned less than $15 million and lost out on the only Academy Award—best original screenplay—for which it was nominated. Critics did love it; indeed, a gang of New York writers, led by Pauline Kael, saved the movie from oblivion. But Diner has suffered the fate of the small-bore sleeper, its relevance these days hinging more on eyebrow-raising news like Barry Levinson’s plan to stage a musical version—with songwriter Sheryl Crow—on Broadway next fall, or reports romantically linking star Ellen Barkin with Levinson’s son Sam, also a director. The film itself, though, is rarely accorded its actual due.
