Continuity: When Rosemary has decided to sneak over to the Castevet's, she removes the towels from the closet shelves. She then tries to shut the door by pushing the towels (on the floor) into the closet. We see that the closet door does NOT shut all the way. Rosemary goes to get a knife, when she gets back to the closet, the door is completely shut, and she must now turn the knob to open it.

Continuity: After the birth, Dr. Sapirstein injects her twice with sedatives but when we see Rosemary's arm as she is recuperating there are no burses or marks that we can see where she received the shots.

Continuity: In the scene after learning she was pregnant, Rosemary cooks herself a "blue" steak (barely seared on either side), yet when placed on the table, and she commences eating, the depth of heat penetration indicates "rare" - much more cooked than "blue".

Continuity: The building manager lets them into the apartment and Rosemary and Guy stand in the hallway as he closes the door behind them. In the next shot Rosemary is already in the kitchen.

Factual error: Dr. Sapirstein's receptionist is making an appointment for a patient on "July the 10th". July 10th 1966 falls on a Sunday and there's no indication that Dr. Sapirstein (witch or no witch) or his receptionist have regular office hours on Sundays.

Continuity: Rosemary opens her suitcase and hands a red book to the doctor. If you look closely, the dress she's wearing has sleeves and is a different one then the previous shot, which is sleeveless.

Continuity: Rosemary and Guy play Scrabble on a rainy day and if you look out their living room it's mid-day. Rosemary feels ill and walks into the bedroom and looking out the window we see that it's still raining but it's now night.

Continuity: The morning after the birth Rosemary wakes up and startles Laura-Louise, and the face of the clock behind the bed is lit up. In the next shot as she looks at it's not lit up. It's also ticking yet the second hand doesn't move.

Visible crew/equipment: Rosemary walks into the party in the Castevet's apartment where she first sees the baby and you can see the shadows of a ton of stage lights and equipment on her shoulders.

Continuity: In his office Dr. Hill tells Rosemary, "I don't believe in witchcraft" and in his close-up the clock and pictures of his kids below the diplomas move closer together between shots.

Continuity: Dr. Hill brings Rosemary into an examining room and turns on the air conditioner so she can rest. Before he leaves we see outside the window and it's daylight, but two shots later we see out the window again and it's twilight.

Continuity: Rosemary gets back into the apartment and gets Elise Dunstan's phone number from the phone book inside her pocketbook. She leaves the pocketbook right next to the phone book but when Dr. Sapirstein comes in the with a sedative she tries get away across the bed and the pocketbook is no longer there.

Continuity: Dr. Hill gets Guy and Dr. Sapirstein to escort Rosemary out of his office and the light on the examining apparatus between the two doors has been moved to the right since they walked into the room, without anyone going near it.

Visible crew/equipment: As he shows them the kitchen the building manager says, "I'd be grateful to go that way myself when the time comes". As he turns around to leave the kitchen you can see the shadow of the camera on his jacket.

Factual error: The story is supposed to take place from 1965 until the baby's birth in June,1966. Yet, before Rosemary is even pregnant, there is a 1967 Chevrolet taxicab sitting at the curb.

Factual error: Rosemary calls Dr. Hill from a pay phone and says, "The baby's due on Tuesday, you remember you told me June 28th" (and June 28th 1966 does fall on a Tuesday). In the previous scene in Dr. Sapirstein's office his receptionist is making an appointment "next week" for a patient and that date is "July 10th" indicating that if Rosemary is due on June 28 th (which she says is next Tuesday) the dates do not match and it must still be the week of June20th which is at least two weeks before July 10th.

Continuity: There's no indication that Rosemary has been reading or even opened up her suitcase while she went from Dr. Sapirstein's office to Dr. Hill, but when she packed her suitcase the red book was on top, now in Doctor Hill's office she opens the suitcase and the red book is on the bottom.

Continuity: Rosemary tells Doctor Hill about Hutch and we get a chance to look at her wrist watch, which says 2:20. In the previous scene as she talks to Doctor Hill in the phone booth he tells her to meet him at his office at 8:00.

Continuity: In Doctor Hill's office Rosemary opens her suitcase and hands the red book to the doctor. When she first takes the book out of her suitcase she has a wrist watch on her left hand, then in the next shot as she hands it to him there's no wrist watch.

Continuity: After Rosemary calls up Elise Dunstan she hears something moving around in the apartment and turns her head to the right in order to see what it is. In the next shot when Guy and the others walk into in the room Rosemary's entire body is turned around looking at them.
