Continuity mistake: In the kitchen when Jan announces that she took up tap dancing, Mike's first button goes from buttoned to unbuttoned a few times during the scene. (00:06:00)
Snow White and the Seven Bradys - S5-E3
Continuity mistake: When Mike rides up on stage he points to the damsel in distress with his right arm extended, but in the closeup it's his left arm extended.
Continuity mistake: In episode 5-8 the girls have their walls wallpapered from pink to a yellow pattern with a white background. In the next episode it is back to the pink walls. The following episode it is back to the new wallpaper.
Plot hole: When Mike was at the meeting and pulled out the Yogi Bear poster, he said he could find the other cylinder, and was told by one of the other men that they had to catch a plane in 30 minutes. After that, he had to find Jan, and then Jan and Marcia had time to go on about 4 rides and then find the sketches and then start their run across the park. There is no way all of that could have been done in less than 30 minutes.
Continuity mistake: During the filming scene near the end of the episode, Bobby's hat transitions from being in his hands to back on his head, untouched.
Visible crew/equipment: When they're all practicing the Charleston, while Bobby's watching from the stairs, everyone is shown dancing from different angles, and in the low angle shots facing the kitchen the top of the kitchen set is visible, particularly when Carol twirls her necklace.
Snow White and the Seven Bradys - S5-E3
Audio problem: When the kids are painting a cardboard tree for the play, they ask their dad what he thinks of it. He then says "you better ask the two poodles next door." As he walks away he seems to almost trip/fall over something. Then the mom is heard laughing, even though she's not in the scene.
The Hustler - S5-E21
Revealing mistake: When Mike's boss, his wife and two other guests arrive at the house for a night of pool, the four guests are greeted at the front door, enter the brick entry foyer, and descend the steps into the living room. As the camera pans to capture the guests entering the living room, the obviously unfinished and unbricked end of the entry platform can be seen in the shot.
Audio problem: Listen to the sounds as the family eats dinner; the same sound sequences keep playing. For example, one sequence of three quick taps of silverware on plates plays several times, followed by another sound that is difficult to identify. (00:21:15)
Continuity mistake: Near the beginning, Greg is painting the shutter green, he gets a phone call and goes inside. The paint bucket falls on Bobby because the ladder falls. Greg sticks his head out the window and asks who took his ladder. The shutter now has no paint on it.
Continuity mistake: When Cindy gets out of bed to write a letter to Joe Namath, they show the wall next to Jan's bed and there is no window. In a previous episode Jan lost the locket out that window that Alice sent her.
Other mistake: When the boys are playing football in the backyard, watch Greg's right foot - at one point he slips on the Astroturf lawn, causing it to wrinkle and exposing a seam on the "grass" lawn. (00:03:20)
Suggested correction: At no time in the show did they affirm the grass in the backyard is real. Many houses, particularly out west where the show takes place, have artificial grass as it's often easier than caring for real grass which tends to dry up easily out west or not grow at all in some areas. Even in A Very Brady Renovation they made sure to use artificial grass for the backyard.
The grass is supposed to be real. There are several episodes where they are mowing the lawn.
But the renovation show was in 2019. In the early 70s artificial grass was only starting to be adopted in sports stadiums. Not used in homes until many years later.
Plot hole: The Bradys and Alice run a relay through the amusement park to get the sketches to Mike at the manager's office. They locate another person to pass the cylinder off to when they get too tired to run. But they all arrive together seconds after Carol gives the sketches to Mike. (00:19:15)
Top Secret - S5-E19
Revealing mistake: Bobby and Oliver are building a house of cards on a small platform sitting on the table when all of a sudden the house of cards collapses. The reason: the platform moves by itself. Clearly it was manipulated off-screen somehow. (00:01:20)
Top Secret - S5-E19
Continuity mistake: The amount of talcum powder in Bobby's and Oliver's hair increases from one shot to the next. (00:14:35)
Continuity mistake: Ken Berry and Brooke Bundy are seated at least a couple of feet from each other in the wide shots, but are right beside each other (arms touching) in the close-ups. (00:01:30)
The Hustler - S5-E21
Audio problem: Bobby is lining up a pool shot. There's a cut to Cindy, and as she says her line, the sound of pool balls being hit is heard. But when the pool table is shown again in the next shot, none of the balls have moved. Also the pool table moves from outside to inside. Lots of mistakes with the balls on the table throughout the game. (00:08:25)
Continuity mistake: The kids walk into the kitchen complaining about the noise from Jan's tap dancing. Peter reaches up and grabs his paper sack lunch and then in the next shot he says "talk about noise pollution" while grabbing his lunch for a second time. (00:09:07)
Continuity mistake: During the goat in the master bedroom scene, the flowers on Carol's side of the bed change during the scene. At first there is a pink flower to the right of a white flower, and then it changes to white flower on right of the pink one. In addition, the whole bouquet looks slightly different in different shots.
The Hustler - S5-E21
Audio problem: There's an ominous mic echo when Bobby is talking with Mike's boss at the pool table, indicating this was filmed on a sound stage.
