Continuity mistake: Minnie gives Rosemary a cup of Lipton's tea as she sits in a chair in front of a book case. We first saw these books when Rosemary sat down and they were all vertical, but then when she gets the cup of tea the books in both shelves are slanting to the left. (02:11:20 - 02:13:20)????
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: 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 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. (01:55:55)????
