Continuity mistake: After she figures out the anagram using her Scrabble game Rosemary unlocks the front door and lets Guy in. They both walk into the kitchen and the book "All Of Them Witches" is sitting on the kitchen table. They walk out of the kitchen only to return later and the book has spun around and is opened to a different page on the table (just about everything else on the table with the chairs included have also moved). (01:30:55)
Continuity mistake: Rosemary and Guy walk back into the kitchen as she shows him the book Hutch gave her and if you look out the kitchen window it's an entirely different time of day then it was a minute ago as they walked out of the kitchen. Several items on the window ledge and countertop have also been moved between the two shots of them in the kitchen. (01:31:20)
Continuity mistake: Guy follows Rosemary into the kitchen where she shows him the book Hutch gave her, "All Of Them Witches". If you look at the calendar at the right of the shot it's obvious someone other than them has been looking at it as the top month is curled up the second time we see it. (01:31:25)
Visible crew/equipment: In their living room, Rosemary tells Guy that she doesn't want Minnie or Roman setting foot in their apartment again after she shows him the book Hutch gave her, "All Of Them Witches". The shadow of the boom mike can be seen going from left to right across the top of the fireplace. (01:32:55)
Continuity mistake: After telling Guy that she doesn't want Minnie or Roman setting foot in their apartment again Rosemary sits down in their living room and reads from the book "All Of Them Witches". If you look closely at the second shelf in the bookcase on the left of the screen several books (primarily a red one) have been added between shots. (01:33:10)
Visible crew/equipment: As the Castevet's leave for the airport, Rosemary and Guy say goodbye to Minnie and Roman in front of The Dakota. As the cab pulls in front of them you can see the reflection of the cameraman and studio lights from across the street in it. (01:34:55)
Continuity mistake: When the taxi cab pulls out taking Minnie and Roman to the airport there's a red car in front of them. The next time we see the cab a few seconds later there's a white car in front of them. (01:35:35)
Continuity mistake: Rosemary looks for her book "All Of Them Witches" and Guy replies, "Oh, I put it in the garbage" as she reaches around the bookcase. In the next shot she's touching a different book with her left hand. (01:35:50)
Revealing mistake: Rosemary crosses 5th Avenue as she goes looking for a bookstore to find more material on witches and a lot of bystanders can be seen staring at the film crew. (01:36:10)
Visible crew/equipment: Rosemary goes back to see Dr. Sapirstein and speaks to his receptionist. After she sits down they cut back to a close-up shot of the receptionist working and you can see the reflection of the camera man's head on the left of the glass file cabinet behind her. (01:40:05)
Continuity mistake: After Rosemary speaks to Dr. Sapirstein's receptionist about an appointment she sits down in the waiting room and the receptionist asks her how hot it is outside. She doesn't move yet several things move behind the receptionist's head in the two shots she's in. The ash trays above the windowed file cabinet behind her move from the right side to the left side and the two small file cabinets above the large file cabinet to her right also move. (01:40:10)
Continuity mistake: As she sits waiting for Dr. Sapirstein, Rosemary picks up a TIME Magazine with the cover story "Is God Dead" (April 8,1966) which has a red border and white lettering on top. In the next shot if you look very closely she's reading another magazine that has a red border and yellow lettering. (01:40:40)
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 28th (which she says is next Tuesday) the dates do not match and it must still be the week of June 20th which is at least two weeks before July 10th. (01:44:45)
Continuity mistake: When we first see her sitting in Doctor Hill's office, Rosemary does not have the white pocketbook beside her on the chair. Later as she reaches down to open her suitcase, the pocketbook appears on the chair. (01:46:45)
Continuity mistake: 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. (01:47:40)
Continuity mistake: 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. (01:47:45)
Visible crew/equipment: In Doctor Hill's office Rosemary opens her suitcase and just before she hands the red book to the doctor a piece of paper held by a crew member can be seen in the lower left area of the screen. In the next shot the doctor's hands are empty so it couldn't have been him holding it. (01:47:45)
Continuity mistake: 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. (01:47:50)
Continuity mistake: 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. (01:48:10)
Continuity mistake: 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. (01:49:10)
Chosen answer: It doesn't have a specific title. It was a lullaby written for the film by Krzysztof Komeda. There's a few variations of the lullaby heard throughout the film, the opening credits version is listed as "Rosemary's Baby Main Theme - Vocal."
