But then I saw Mr. Fox, and was so astonished by it, and realized that, in this case, I really did need to read the book before I could even begin to get my head around its movie adaptation. Because I needed more knowledge of Roald Dahl’s book in order to appreciate just what level of astonishing Wes Anderson’s movie is. Was it merely that Anderson was standing on some astonishing shoulders? Or was he standing on astonishing shoulders and then bulked up with some astonishing shoulders of his own?

Because I was sitting there in the screening room thinking, Wait. Did Dahl invent this notion of Mr. Fox (the voice of George Clooney: The Men Who Stare at Goats, Burn After Reading) being asked to settle down from his felonious thieving of the local farmers’ geese and chickens and hams and such by his wife, Mrs. Fox (the voice of Meryl Streep: Julie & Julia, Doubt), when she learns she’s got a kit in the oven? Did Dahl invent the notion that, years later, he might seek to return to his life of crime, and would do so on the sly so as not to get in trouble at home? Is it down to Dahl that Mr. Fox has a lawyer -- Mr. Badger (the voice of Bill Murray: Get Smart, The Darjeeling Limited) -- and that he needs a lawyer because, come on, no one wants to get into real estate and take on a mortgage without someone looking out for you? Did Dahl concoct the nerdy but nice Fox child Ash (the voice of Jason Schwartzman: Funny People, Walk Hard: The Dewey Cox Story), who likes to wear a white cape in honor of his favorite comic book, White Cape? Did Dahl invent whack-bat -- think cricket meets baseball, with explosions -- the hilarious team sport Ash is no good at in school? Did Dahl write dialogue that included frequent substitutions of we-know-precisely-what vulgarities with cuss, as in, “What the cuss?” and “Why the cuss didn’t I listen to my lawyer?”

Could you read Dahl’s Fantastic Mr. Fox, I wondered, and imagine the Rolling Stones playing in the background?

Does, in short, Dahl’s book feature drinking, smoking, and fake swearing among woodland creatures, stuff blowing up, attempted mass drowning in alcoholic cider, and numerous counts of attempted talking-animal murder?

I didn’t think so, but I had to check to be sure.

As it turns out, these things have no place whatsoever in Dahl’s story [Amazon U.S.] [Amazon U.K.]. (Well, there are numerous counts of attempted talking-animal murder, but that’s it.) It is not a metaphoric tale about marriage and compromise. It is not a story about how all of us are pretty fantastic, given our individual skills and talents, even if not everyone recognizes them at first. (Well, maybe it’s a teeny bit about that.) It is not a story about how our particularly human hopes and dreams look simultaneously ridiculous and poignant when seen through the perspective of critters not generally known to be concerned about school grades, property values, finding a middle ground between being true to ourselves and attentive to the needs of those we love, and the like.

Dahl’s version is a story about a clever fox who steals fowl from human farmers, and the farmers try to stop him using some surprisingly violent means, and that’s pretty much it. It is, in fact, plenty charming and plenty whimsical on its own, so much so that it could be hard to imagine how it could get much craftier.

But not for director Wes Anderson, and his coscreenwriter Noah Baumbach (who cowrote The Life Aquatic with Steve Zissou with Anderson, and is a filmmaker in his own right: Margot at the Wedding). They looked at a sweet-and-sour children’s story through a peculiarly skewed eye and said, This can be so much more. And they turned it into something touching and funny, and magically absurd and at the same time pointedly real. They turned it into something genius.

It’s in how their Fantastic Mr. Fox is like Ocean's Eleven made by Rankin and Bass. (It makes you wish that when someone like Robert Zemeckis decided to make a kiddie version of A Christmas Carol he’d turned to Rudolph's Shiny New Year for inspiration, not video-game cut scenes.) Or by Nick Park -- oh, you know who Nick Park is: he’s the Wallace and Gromit guy -- a cartoon that’s really and truly suitable for grownups and children alike, shrewd and witty in both its style and substance. Some of the sharpest, most observant dialogue of the whole year is in this script: “I enjoyed it, but I shouldn’t have done it,” says Mr. Fox about his return to crime; “If what I think is happening here is happening here, it better not be,” says Mrs. Fox when she suspects her husband is up to no good. Some of the most striking and most unexpected visuals in ages are here. On the small scale, there’s something about Mr. Fox’s little mustard-colored corduroy suit that is inexpressibly magnificent. On a larger scale, the accumulation of detail that creates this world, from pocket squares to paintings on the walls to the printed pattern on Ash’s little-boy underpants, makes it feel utterly authentic, as if this were a real place we were visiting, and a place we’d actually like to visit, where the people are as weird and as wonderful and as obsessed with living their own lives as, well, we ourselves are. It’s in how the lack of fluffy cuteness in Anderson’s stop-motion-animated characters makes them characters you can really love -- even when they’re frustratingly complicated and contradictory and just confidently themselves -- instead of something to awww over. It makes it easy to share their exuberance and their dissatisfaction and their disasters and their triumphs.

It’s in how Fantastic Mr. Fox is perfectly, deliciously odd, and just plain perfect.
