Continuity mistake: Hutch pays Rosemary a visit and is shocked by her appearance as they sit and talk in the living room. If you look closely there are two cushions placed between the record player and the record holder on the left in the screen. Two shots later when Roman walks into the room there's one cushion there and Hutch didn't move. (01:02:25)????
Continuity mistake: Hutch calls wanting to speak to Rosemary who's lying down on the right side of the bed. Guy brings in the phone and places it on the bed for her. When he puts it down the blanket on the left side is perfectly smoothed and tucked in but when he takes the phone back from her the blanket is messed up, and she hasn't gone near that side of the bed. (01:08:30)????
Continuity mistake: Hutch and Roman talk about vitamins and Dr. Sapirstein in Rosemary's living room. Look at the brown chair to the right of the window, it's obvious someone's been sitting in it as the back is all ruffled up. In the previous shot before Roman walks into the room it's not. (01:04:15)????
Continuity mistake: The phone rings while Rosemary straightens up the living room. Guy answers it and after the conversation they both go back into living room. No one has gone near them but the pillow on the left of the window and the magazine rack below it have been moved. In fact they move three different times. (00:33:35 - 00:35:05)????
Continuity mistake: Rosemary doesn't want to wear the necklace that Minnie gave her so she puts it in a drawer in her dresser as she says, "Tannis anyone?". When she walks up to the dresser there's a red handbag on the right of it that's not there in the close-up shot as she looks in the mirror. (00:33:15)????
Continuity mistake: Rosemary and Guy are interrupted on their romantic evening together by Minnie Castevet knocking at the door. Guy gets up to answer it and we see his two glasses, the smaller one filled with wine and a larger one filled with water placed right next to the candle. Two shots later when he returns, the glass of wine has been moved to the right and the candle has been removed. (00:38:30)????
Continuity mistake: Rosemary gets sick from the mousse and Guy brings her into the bedroom. Several things have been rearranged since the last time we saw it. The lamp on top of the shelf has been removed and we see a different lamp on the end table and the bed now has a head board behind it. (00:34:10 - 00:42:00)????
Continuity mistake: Guy is lying down on the sofa as Rosemary shows him the necklace with the tannis root inside. His right ankle is leaning over the edge of the sofa right next to the lamp. Two shots later Guy says, "Well if you took it you ought to wear it" and the lamp has been moved a foot to the left of his ankle. (00:32:50)????
