Corrected entry: After Terry Gionoffrio jumps to her death Rosemary lies in bed and hears Minnie say, "Sometimes I wonder how come you're the leader of anything" as we see a nun mouthing these words. If you look closely her lips do not match what she says at the beginning of the sentence but do at the end.
Corrected entry: At night, Guy tells Rosemary, "I'm gonna get an ice cream cone, you want one?" She says yes and proceeds to roll over and cry. We hear an over-dub of the doorbell ringing, but this is wrong because Rosemary doesn't ring the bell until slightly before 11:00AM the next day, as we see in the next shot. One might say that it's Guy ringing the doorbell as he goes out for ice cream, but both overdubs sound exactly the same and this could not happen as the sound would have to come through the wall as she lies in bed.
Corrected entry: When Minnie comes over to talk to Rosemary for the first time, right after Terri's death, she says that she was buried the day before. But when she is inviting Rosemary and Guy over for dinner, she says it's the first night they have been alone since her death.
Corrected entry: In the scene where Rosemary and Guy come home to find policemen around a dead Terri's body, Guy tells one of the officers that Terri was staying with the Castevets in apartment 7-E. However, later in that same scene, when he and Rosemary meet the Castevets, he tells them that he and Rosemary live in apartment 7-E.
Corrected entry: If Rosemary gets pregnant early in the month of October, as shown on the calendars in the film, she should give birth around mid July, not June, as the doctor predicts.
