One of the characters that Greg was asking "Where's Marge?" is Lloyd Schwartz. He is Sherwood Schwartz's son and a director on the show.
The Racer, the "big" roller coaster that the Bradys ride at the end of this episode, still stands today, exactly as it did when the park opened 35 years ago. The paint and car colors are even the same (white wooden coaster, with red and blue cars that "race" each other). The only difference is that the cars closest to the concourse race backward--it's not for the weak-stomached. Tame by today's standards, the Racer was once considered a "major" coaster. Being 35 years old, and wooden, the ride is not a very smooth one, either. Much bigger and newer coasters on metal tracks can be found at Kings Island, but the Racer retains its Coney Island-style charm and remains a "fan favorite" at the park.
When the family takes one last trip on "The Racer" roller coaster, the footage shown either is from both the left and right tracks, or the footage is flopped for part of the scene.
When Mike finally delivers the plans to the park administrators, it is raining. One can see a puddle by Jan's feet, and the raindrops hitting the water. Throughout the episode, the sky is clear and nearly cloudless.
In this episode, it is implied that the Board of Directors of the park is based in New York City. In reality, the parent company that operated Kings Island at that time was based in Cincinnati.
The route taken during the climactic 'William Tell Baton Relay' makes no sense at all given the layout of the park, unless one assumes that the Bradys got extremely lost and disoriented in the park.
REPLY: I've been to Kings Island about 50 times; it's VERY hard to find your way around the park if you aren't familiar with its layout.
When Jan and Marcia are searching the antique car ride alongside the track. When the ride attendants saw Marcia beside the track, they should have at least asked her to leave the ride area.
When Carol and Alice get off the "Wheel of Fortune" ride, they exit the ride through the ride entrance and empty queue line.
In the establishing shot of the "Wheel of Fortune" ride, we see an empty queue. Throughout the episode, it is implied that the park is quite busy, leading one to believe that there would be a line for almost all of the rides.
When Greg is talking to various costumed animals in a search for Marge, one of the employees takes off the head of his costume. This practice is strictly forbidden by the park, in that it ruins the illusion of the character. It is because it was Sherwood Schwartz son.
At the restaurant scene, we do not see Mike removing the sketches from the one tube before inserting Marcia's poster.
Throughout the entire restaurant sequence, there are continuity errors in the background, most noticibly with the "Flying Dutchman" swing carousel (for a photograph of an identical ride, click here, and scroll down). Throughout the scene, the ride appears to jump from one point to another in the ride cycle in an incongruous fashion, from just beginning the ride cycle in one shot, to just ending the ride cycle in the next.
The first time that the family rides the large wooden roller coaster (known as "The Racer"), one can see the "Flying Carpet" slide to the left of the roller coaster, due to the 'flopping' of the image. In reality, the slide was to the right of the ride. Later in the same sequence, it appears that the camera is now on the opposite track, implying that footage from later in the ride was not flopped.
During the establishing shot of the "Monster" ride in operation, the queue is seen empty. All other shots of the park show that the park is quite busy, and the queue lines are quite full.
When Mike, Greg, and Peter are finished at the first game booth, Mike tells Greg to pay the attendent. Usually, one pays up front for the games.
(Greg tries asking the girl at the game booth out)
Marge: I'm filling in for my brother. He's an animal.
Greg: Aren't we all?
Paramount's Kings Island Amusement Park really does exist in real life.
This is the last time we see the Brady family leave the Paramount lot. Unlike most shows, the Brady's actually went on location.
In 2005, when the park (then known as Paramount's King's Island) put together a promotional video for their new ride, they spoofed this episode, with the park's two Public Relations officers playing the roles of the entire Brady Family, and Mike's plans being the for the new attraction.
Also mentioned on "Pop-Up Brady" was that the overdub dialogue had to be re-recorded because of fan background noise. Not explained, though was the strange "click-click" sound you heard all throughout this episode!
This episode was featured on the VH1 Series "Pop Up Brady."
When taping the final scene where the family rides the rollercoaster, Robert Reed objected at first because he didn't think the camera was secure on the ride. The crew finally decided to check the camera and realized Reed was right, and properly secured the camera. Had they not done this, it could've resulted in the camera flying off causing serious injury or even worse.
The ironic thing about this episode is the fact that King's Island featured many of the characters created by Bill Hanna and Joe Barbera, while the Brady Kids cartoon series was produced by Hanna-Barbera's main rival during the seventies, Filmation.
This was the final "Brady vacation" episode in the series. Unlike other sitcoms (which used often stock footage of exotic places and filmed on a sound stage in Hollywood), the Bradys actually went "on location." This time, to help promote King's Island in Cincinnati, which had recently opened.
The Hair Bear Bunch
The animal suit that Greg dons is Hair Bear from the early '70s Hanna-Barbera cartoon "The Hair Bear Bunch."
The William Tell Overture/Lone Ranger Theme was cleverly played during the race to get the cannister to Mike.
