Continuity mistake: When Aunt Clara tells Sam not to worry about Darrin because she has her book of spells, there's a closeup of the book with its binding facing left and Clara pointing to the large title "Spells and Incantations" on its cover, but in other shots Clara's holding the book with its binding facing right (we see Vol. 7 on the binding) so the cover is facing the opposite way, and there is no title on the cover. (00:14:00)
Serena Stops the Show - S6-E22
Revealing mistake: The face of the double can be seen when Samantha and Serena come from the kitchen. (01:10:00)
Continuity mistake: Aunt Clara crashes into the pagoda and is helped up by Darrin and Samantha. They head inside and you can see Aunt Clara's purse sitting in the pagoda to the bottom left. But when all three enter the house, Aunt Clara is now carrying her purse. (01:14:00 - 01:20:00)
Samantha the Dressmaker - S2-E22
Revealing mistake: When Samantha and Endora are in Paris reviewing models in dresses, the models are frozen because Samantha and Endora are not supposed to be in the dress shop. One of the models, instead of being frozen, is seen blinking her eye and moving slightly.
Follow That Witch (2) - S2-E29
Factual error: When Charlie Leach is walking back to USA from Mexico he stops close to a sign that reads "Nueva York 2138 miles". Either the sign should read "New York..." or the distance should be stated in kilometers.
Other mistake: In the opening scene, Endora disappears then reappears for Tabitha. If you watch closely, just before she reappears you can see the shadow of Agnes Morehead/Endora on the wall behind the couch quickly coming back to the couch for the camera cut to recapture her.
Revealing mistake: The series is supposed to take place in Westport, CT. Westport, CT doesn't have palm trees or the California mountains. Several shots outside of the house reveal the mountains and palm trees are when driving in several episodes.
Samantha's Witchcraft Blows a Fuse - S8-E25
Continuity mistake: The hole (square cut out) is visible in the carpet before they fall through. Also, when Dr. Bombay "cures" Samantha and she floats, the hole in the floor beside the couch is gone. Dr. Bombay fixed the floor in the next shot (when asked). The floor without the hole is visible when Dam floats up and when Darrin and Bombay walk over to her.
Samantha's Thanksgiving to Remember - S4-E12
Factual error: I noticed a grandfather clock when they all arrived in Plymouth (in the right corner). I won't assume this is the first Thanksgiving since the colony is built up and seems established. Plymouth was from 1620-1690s. I had to research but apparently there would not have been an ornate grandfather clock available. The first clocks were built around the time but were not common - especially in an American colony like Plymouth struggling to survive.
Birdies, Bogies, and Baxter - S4-E7
Other mistake: In the scene at the end where Baxter is saying "You learn something about how you take defeat, I never thought I would be learning something about myself" the background behind Baxter doesn't match the background when the shot is a wide shot showing the out door course, trees and buildings. Instead it looks like a painted backdrop perhaps filmed separately for the closeup. It's definitely not where Baxter is standing in wide shot.
Naming Samantha's New Baby - S6-E6
Factual error: When Mr. and Mrs. Stephens are driving in the convertible. In second shot, there are at least 2 tall palm trees along the road. Morning Glory Circle is supposed to be a NY town. There are no palm trees growing in NY. It's obviously shot along a CA road.
It's So Nice to Have a Spouse Around the House - S5-E5
Continuity mistake: Samantha removes a spell cast by some other witch; it's a series plot point in many episodes that Samantha cannot undo someone else's spells.
A Most Unusual Wood Nymph - S3-E5
Continuity mistake: When Samantha goes back to the 15th century, Geri O'Toole is wearing a yellow dress. When Samantha pops back home, Darrin is wearing Thea Ames hit but Geri is wearing a pink dress. It all happened the same afternoon/evening. Geo should still be wearing the same yellow dress.
Humbug Not to Be Spoken Here - S4-E16
Other mistake: In the previous episode, I've Got Your Nanny Right Here, Samantha tells Darrin "nobody travels by broom stick anymore. It's obsolete." She takes Mr. Mortimore to North Pole by broomstick.
Samantha for the Defense - S3-E14
Factual error: Benjamin Franklin is portrayed as a gentleman in this episode and the previous My Friend Ben episode. In this episode he dates Aunt Clara at the end. In reality, Benjamin Franklin was a cad, a womanizer and a playboy. He was a marvellous man - a genius - but treated women terribly refusing to marry his common law wife, abandoning her for years while he played with other women in Europe... and treated his daughter like a second class citizen.
Other mistake: When Samantha and Clara "pop" into town searching for Ben, they appear on the sidewalk a few feet in front of others, who don't react to their sudden, magical, appearance.
George Washington Zapped Here (2) - S8-E22
Other mistake: This episode is merely a redo of the Ben Franklin episode in Season 3. The plot is the same. The dialogue in many parts is EXACTLY the same. The courtroom dialogue is the same as the courtroom episode of Ben Franklin. In both episodes, Samantha acts as the attorney even though a lay person is prohibited by law of practicing law... pretending to be an attorney.
George Washington Zapped Here (1) - S8-E21
Continuity mistake: The door/hallway leading to kitchen which has always been visible outside and opposite the den has disappeared. It is now a hideously wallpapered wall with a picture.
There's Gold in Them Thar Pills - S3-E33
Continuity mistake: In the opening scene, when Dr. Bombay tells Endora that his practice is "limited to our own people". The scene is edited and is chopped. You can see the edit when watching Dr Bombay.
Bewitched, Bothered and Infuriated - S3-E31
Continuity mistake: Louise's outfits change. She's wearing a yellow shirt outfit when she first arrives. It changes when Samantha sends her back. If she is sent back she should be wearing the same yellow outfit.
