James Best and Ben Jones each boycotted parts of season 2 due to disputes with the producers, while John Schneider and Tom Wopat missed most of season 5 as contract holdouts. Catherine Bach doesn't appear in season 3's "To Catch a Duke".
Even the General Lee is missing from one episode! Granted, that episode ("Mary Kaye's Baby") was only the third episode of the show's first season, so the car probably wasn't established enough as a "star" in its own right for its absence to have been noticed by many viewers at the time.
Averted by John and Tom when the whole cast offered to join their boycott of season 5. Catherine mentioned offering to walk off with the two of them, but they told her not to. According to one source, they said that the reason they left was "man's work," but another simply said that they felt that if all three of them walked, there'd be no show to come back to. Also averted by Denver Pyle and Sorrell Booke, the only cast members to appear in every episode.
Rosco is occasionally shown with a fishing pole. Apparently he is an avid fisherman, just like the actor portraying the role (James Best).
Morgan Woodward parodies his most famous role, Boss Godfrey, in "Cool Hands, Bo and Luke"
In one of the BanditAction PackMade For TV Movies (based on the Smokey and the Bandit films) John Schneider plays a sheriff going after Bandit who seems to have gotten a passing grade (though not all As) from the Roscoe P. Coltrane driving academy.
California Doubling: Apart from the first few episodes, which were shot on location in Georgia.
Sorrell Booke died in 1994, three years before the first reunion movie aired. Rather than hire another actor who could reasonably play Boss Hogg, it was decided to also reveal that Boss had passed on. A tender scene is seen early in the film, where Rosco sees a large portrait of Boss hanging in his office and gets emotional. It is revealed that Boss had died not long before the events of the first reunion movie, the circumstances of which are not told.
Denver Pyle died in 1997, just months after the first reunion movie aired. The writers of the second reunion movie, aired in 2000 – which depicts, in part, a homecoming celebration in Hazzard – make several references to Uncle Jesse being deceased but well thought of, some two years after the Duke patriarch's passing.
Creator Backlash: Most of the cast were of the view that the scripts could have been generally better (the writers, in turn, said they were straightjacketed by executive producer Paul Picard's guidelines - that's why, for instance, it almost never gets dark in Hazzard County). Tom Wopat felt the cartoon had better writing ("Some of them are pretty funny. And the car flies!").
They also weren't too keen on Warner Bros. mandating the use of miniature work to make the car sequences ever more spectacular in the later seasons. Neither were the stunt personnel.
Most of the cast of the film doesn't look back fondly on it. Seann William Scott said he enjoyed filming it and is still friends with his castmates (particularly Johnny Knoxville), but didn't like the final product. Even his family was embarrassed for him when he invited them to the film's premiere.
Enos Strate was introduced as a recent police academy graduate and younger than Bo and Luke (probably around 19-22), and it was mentioned several times that Enos was childhood friends with the Duke cousins, but Sonny Shroyer was in his mid-forties at the time, and about 20 years older than any of the Dukes. Shroyer has always looked much younger than he actually is, though, so the casting worked.
John Schneider was 18 when he was hired to play Bo, whose character is said to be in his mid-20s when the series began. (Indeed, the casting directors were looking for a mid-20s man, and Schneider has recalled in interviews where he lied about his age (and background) to audition for the part.)
Directed by Cast Member: Multiple instances, with episodes directed by James Best, Sorrell Booke, Denver Pyle, John Schneider and Tom Wopat (Schneider directed the Series Finale, which he also co-wrote - he was the only cast member to write an episode).
Dueling Shows: Part of the ratings decline during the second half of the series run was attributed to the presence of Knight Rider on NBC. While not airing directly against each other, both shows vied for the attention of a largely younger audience with an interest in souped up cars. As a result producers began to increase stunt and jump sequences featuring the General Lee. The rivalry between the series was played up in a satirical cross over story between the two shows in a 1983 issue of Cracked magazine.
Despite all the southern charm (and southern stereotypes) of the show, none of the four main actors were actually from Dixie. (John Schneider was from New York, Tom Wopat was from Wisconsin, Catherine Bach was from Ohio and the '69 Dodge Charger was from Michigan.) Due to the popularity of the series, they have been accepted as honorary Southerners, however.
Meanwhile, Denver Pyle (Uncle Jesse) was from Colorado and Sorrell Booke (Boss Hogg) was from Buffalo, New York. (Booke was actually a graduate of Yale.)
In fact, only James Best, Ben Jones, and Sonny Shroyer were southerners among the main cast.
Fat Suit: In real life, Sorrell Booke was actually much slimmer than Boss Hogg and had to wear padding under his outfit to appear heftier than he really was.
Harpo Does Something Funny: In later seasons Sorrell Booke and James Best were often allowed to ad lib once the producers realized the duo's comedic chemistry. Both Best and Booke submitted ideas to the writers, which were almost always used; several of these acts were used in their real-life birthday party package.
Hilarious in Hindsight: Daisy's main vehicle during the series' run is a Jeep Wrangler. Jeep at the time was owned by independent automaker American Motors (whereas most of the other vehicles shown were produced by Chrysler Corporation). Two years after the series' 1985 conclusion, Chrysler would purchase American Motors; with Jeep remaining one of the company's top performers.
Keep Circulating the Tapes: In July 2015, two weeks after Dylann Roof was arrested in the killings of nine African Americans at a church in Charleston, S.C. (after which, along with his racist manifestos, photos of him posing with the Confederate flag became public), Warner Bros. stopped licensing Dukes of Hazzard merchandise, including the General Lee (which has a large Confederate flag painted on top). Shortly thereafter, TV Land pulled reruns of the show off its schedule, effective immediately. It is unknown when, or if, the show will return in the future.
Jerry Rushing, a real life ex-moonshiner whose reminisces were used as the basis for Moonrunners (and who had a Real Person Cameo in that film), went on to sue Warner Bros. for developing Dukes without giving him credit.
The Red Stapler: "Daisy Duke" shorts, tight jeans cut off just below the buttocks, remain in fashion among teenage girls (though the name hasn't been in use since the early 90's), becoming stock jailbait attire.
Too Soon: Don't expect to see this on television again any time soon after the Charleston church massacre perpetrated by white supremacist and Confederate sympathizer Dylann Storm Roof. The outpouring of white nationalism from the alt. right, which includes both confederate sympathizers and neo-Nazis, two years later overshadowed the charm of the show's southern pride even further.
Word of God: While never spoken of in any episodes, Creator Gy Waldron has given a back story explaining that Uncle Jesse took in and raised Bo, Luke and Daisy upon their parents' death in a car crash.
Written-In Absence: Both in Season 2. Sonny Shroyer (Enos) was missing for two episodes due to appendicitis (they gave Enos appendicitis as well), while James Best (Rosco) left for a while due to a contract dispute (so they shipped Rosco off to the academy for re-certification). Also, John Schneider was absent for an episode because he was filming a TV movie (this was before the great merchandising dispute in season five), so Bo spent a weekend with the Marine Corps. In season five, it's explained that Bo and Luke left to join NASCAR.
