Continuity mistake: Rosemary tries a third time to figure out the anagram with the Scrabble letters and comes up with "elf shot lame witch". She tries a fourth time and comes up with "how his hell fact me". She decides to give up and begins putting the letters away when she has an idea and pulls the book close to her and we see the wrong set of letters back on the floor "elf shot lame witch".

Continuity mistake: 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. (02:06:45 - 02:07:35)Ral0618
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: 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)????
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)????
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: Before she enters their apartment and sees her baby, Rosemary walks back to the closet that connects her apartment with the Castevet's and as she opens the door we see yellow linens on the top shelf. Several shots before as she takes the shelves down these yellow linens fell on her head and were not put back on the shelf. (02:05:25 - 02:07:40)????
