A forgotten literary movement

In my dream, I was explaining to various friends and family members what was troubling me:

"This is driving me crazy. I remember that there was a literary movement in the early 20th century, and they had a short, simple name -- but I can't remember what it was, and I can't find any reference to it anywhere! It wasn't the Beatniks, although the two movements had a lot in common. This movement was earlier than the Beats, sort of a precursor I suppose, but they had a name just as simple and memorable as Beatniks. Something like Rat Pack, maybe? Not that, of course, but that sort of name. The strange thing is that I can't remember the name of a single figure from this movement, although it feels is if they're all on the tip of my tongue. When I try to think of their names, all I can come up with is Francis Scott Key, which obviously isn't even the right century. I can't name any of the novels, either, though I do vaguely remember one of the movies associated with the movement. It was called The something Kid -- like The Topeka Kid or something like that, or maybe just The Kid -- and I can remember what the picture on the DVD case looked like: black and white photo with a young boy standing there in oversized clothes and -- oh, I can't remember what those hats were called, either, but one of those hats, you know, like you'd wear in a Guy Ritchie movie. One of their themes was that kids grow up too fast, and their work was a bit sentimental sometimes, but there was also a certain element of tough-guy posturing. They foreshadowed film noir in certain ways, I think you'd say. Anyway, that DVD apparently no longer exists. I can't find any trace of it anywhere. . . ."

I gave this explanation to one person after another, and no one had any idea what I was talking about -- with the exception of one of my brothers, whose only suggestion was, "Wasn't there a group of writers around that time called the Schmucks?" I became convinced that this was some sort of Mandela Effect -- that this whole literary movement had been retroactively erased from history, leaving only a few fragmentary but insistent memories in the minds of a few people like myself.

⁂

Upon waking, I figured that I had been describing garbled memories of F. Scott Fitzgerald (full name Francis Scott Key Fitzgerald) and the 1921 Charlie Chaplin film The Kid -- but would anyone say that Fitzgerald and Chaplin were part of the same "literary movement"? And the movement of which Fitzgerald was a defining member was given the boring, nondescript label Modernism -- nowhere near as cool or memorable as Beatniks or Rat Pack. Or maybe Lost Generation was the name I was trying to remember? Anyway, a very strange dream.
