Other mistake: Although Diane Murphy played "Annabelle", she is listed in the closing credits as having played "Diane". (00:25:00)
Other mistake: At the end of a scene showing the dog, the scene is reversed (mirror image) for a moment. (00:08:50)
Tabitha's Very Own Samantha - S6-E19
Other mistake: The Ferris wheel starts turning before the operator pulls the handle to start it. (00:09:55)
Other mistake: Samantha is reading a 4-line note from Endora. The paper is semi-transparent and in a shot from the front, we can easily see the writing through the paper. However, after the note is "twitched" into a second, shorter note, there's another shot from the front - and the lettering looks exactly the same as it did before. (00:16:40)
The Short, Happy Circuit of Aunt Clara - S3-E9
Other mistake: When Louise returns, when the cow is in the living room, she says Samantha has given her the "wrong jacket." When she leaves again, she takes the same green jacket with her.
Samantha's Wedding Present - S5-E1
Other mistake: When Darrin is first shrunk we see that his clothes are unaffected by Endora's spell (they don't shrink). So, when he was popped back to normal heights, his clothes shouldn't be affected, and he would burst out of them. We already know his suit changed colors.
And Something Makes Three - S1-E12
Other mistake: While Gladys Kravitz is standing in front of her house, which is across the street from the front of the Stephens' house, Gladys sees the Stephens' backyard just as Sam zaps a swimming pool and then zaps it away, but since the Stevens' backyard is located behind the house where the living room and dining room are, this would be impossible even for nosy Gladys Kravitz.
Witches and Warlocks are My Favorite Things - S3-E3
Other mistake: The exterior scene when Clara parachutes in is not the real outside we see throughout the show with neighbors including the Kravitz across the street and fewer trees...and no pine forest. Also, it's obvious Marion Lorne, who was about 80 at the time, was sitting on a swing like apparatus being lowered... understandably.
Samantha's Witchcraft Blows a Fuse - S8-E25
Other mistake: When the police pull up outside the Stephens' home, it is a set shot with fake background. The "road" doesn't match the outside of Stephens' neighborhood shown throughout the series with the Kravitz house across the street (and not a pine tree forest as shown here).
Other mistake: The map behind the officer is of Southern California. The series is supposed to be set in the NY tri-state area. (00:12:45)
Other mistake: This is a remake of season 1 episode when Paul Lynda makes his first appearance as Harold the driving instructor for Samantha.
Suggested correction: This is trivia at best, but the episode isn't really a remake of an earlier episode. Here Samantha teaches Uncle Arthur (Lynde) to drive and in season 1 Harold (Lynde) taught Samantha to drive. But the same actor playing multiple roles in a series is never a mistake.
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.
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.
Suggested correction: This isn't a mistake. At best this is trivia. "Bewitched" had several episodes that were remakes or similar storylines of previous episodes and they're not the only show to do so.
I, Darrin, Take This Witch, Samantha - S1-E1
Other mistake: As Darrin tries to catch the moving ashtray, Samantha is smiling at the hilarity and raises a smiling glance at the camera crew. Possibly brought on by their own laughing. (00:09:49)
