If NASCAR Canadian Series driver Gary Klutt was casted in the Arthur movie for adults, he would be casted as the Butler/slave of the Read household.
Gary Klutt would be trained to be a butler by Bailey, the butler of the Crosswire household.
Gary Klutt would be fat and overweight in this movie instead of being fit and muscular like how he is in real life, and Gary Klutt would be animated as having his hair like the boy pictured below while providing his voice in this movie.

Gary Klutt’s duties would be the same as Bailey’s in the Crosswire household. And Gary Klutt would do exactly what the Reads tell him to whenever they tell him to do it, would be highly obedient and respectful, would eat whatever the Reads put in front of him; and one of his duties would include using his commercial truck & bus driving skills, race car driving skills; and mechanical vehicle maintenance and repair skills to maintain the Reads’ collection of over 50 vehicles, the farm Jeep CJ-6 and the farm Land Rover Series II, and the International 886 tractor that the Reads own.
And it is the farm Jeep CJ-6 and the farm Land Rover Series II, and the International 1086 tractor with mower attachments that Gary Klutt would cut the grass for the Reads, all 13 acres of their property. The International 786 tractor has the D360 engine, a normally aspirated version of the DT360 diesel engine. The international 886 tractor also has a climate-controlled cab over the operator station, an expensive option that the Reads had opted for when they had purchased the tractor in 1977.
A plate of grated cheese and a plate of croutons would be all that Arthur’s parents would ever feed Gary Klutt.
Arthur’s parents buy Gary Klutt a diesel powered version of the Pontiac T1000 (Pontiac version of the Chevrolet Chevette, Opel Kadett C; and the Isuzu Gemini) with the Isuzu 4BF1 diesel engine for Gary to run errands in as the household butler. Jane & David Read consider it moot with the Chevette/T1000 being as awful of a car they are in the case of them buying a car just for their butler to run errands on behalf of the household.
As awful of a platform the GM T-platform is, the car that Jane & David Read buy their butler is the rarest of the U.S built T-cars because of the Pontiac being rarer than the Chevrolet, Isuzu-powered diesel Chevettes being rare; and Isuzu-powered diesel T1000s being even rarer.
When Gary Klutt’s duties as a butler call for a pickup truck, Arthur’s parents Jane & David have him covered there, too. They’ve also purchased Gary Klutt a Dodge Rampage-the pickup truck version of the Plymouth Horizon/Dodge Omni with the K-Car 2.2 liter 4-cylinder engine, the A413 automatic transaxle; and a center-band two-tone paint job. Like with the Pontiac T1000, they consider it moot with how awful of a vehicle the Dodge Rampage; like with every other K-Car or Chrysler L-platform is as this is one of two vehicles intended for their butler to run errands on behalf of the household.
Purchasing the Dodge Rampage is the one and only time Arthur’s parents support one of their foes-the evil Iacocca, who, at one point in time in the movie; shows up at the Reads’ front door and Arthur’s mother Jane then rambles on to the evil Iacocca about how they’ve found a bunch of better cars and they bought them all, mimicking Iacocca’s famous tagline in the commercials for the Chrysler Corporation that he had starred in.
The purpose of having Gary Klutt casted as the Butler of the Read household would be to execute the differences in personalities and family dynamics in the characters in this movie-such as Arthur & his parents versus the other family that D.W & Katherine are a part of versus the mainstream children (such as Francine, Buster, and Prunella to name a few) that attend and reside at the Catholic boarding school.
And also, to execute the contrasting values of Jane & David Read being strict to Gary Klutt as their Butler versus not being strict to Arthur, letting Arthur do whatever he wants, letting Arthur have much of whatever he wants, being soft on Arthur; and letting Arthur eat whatever he wants.
I personally do not like the haircuts on the little boys that Gary Klutt is standing adjacent to in the photo below.

Gary Klutt should never be allowed to dress to the nines.

Gary Klutt should also never be allowed to participate in any mainstream sports.
It shall be brought to your attention that as the Reads’ Butler in this movie, that Gary Klutt will be forced to listen to Adult Contemporary, Jazz, and Easy Listening music; and they won’t have any tolerance for the music that the band whose concert that Gary Klutt had attended when he was in Detroit one time.
