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)????
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)????
Continuity mistake: 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". (00:59:00)
Continuity mistake: Rosemary and Guy Joke around in their apartment after dinner with the Castevet's and Guy unbuttons and pulls his shirt out of his pants as he gets undressed. He walks off camera for few seconds and comes into view again with his shirt tucked back in his pants, only to take it off again a few seconds later. (00:29:30)????
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)????
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.
