Continuity mistake: Guy talks about Hutch and says to Rosemary who's lying in bed, "I think those boys adventure stories are going to his head". The pile of magazines to her right moves toward the edge of the night table between shots without being touched. (01:09:10)
Continuity mistake: Hutch calls and wants to speak to Rosemary who is lying down in bed reading a book. After the conversation Guy asks her, "What was that?" and the book she was reading is now flipped over and underneath the phone. (01:09:10)
Continuity mistake: When Rosemary goes to visit Minnie to inform her she's going out for a while, she rings the doorbell, and we hear it chime. Later, at Minnie and Romans while everyone is gathered around the baby, another guest arrives, rings the doorbell, and it's a very different chime. (01:10:13 - 02:12:08)
Factual error: Rosemary goes out to meet Hutch at the Time Life Building and we see the marquee at Radio City indicating that "The Happiest Millionaire" staring Fred Mac Murray and Tommy Steele is playing. The problem here is that it's already been established by the calendar on the Woodhouse's kitchen wall and by the Pope's visit it that this is winter 1965, but "The Happiest Millionaire" didn't premier until 1967. (01:10:25)
Revealing mistake: Rosemary waits for Hutch at the Time Life Building and a crowd of bystanders can be seen watching the filming as she stands up when she thinks she sees him walking towards her. (01:10:50)
Visible crew/equipment: After Rosemary calls Hutch and finds out he's ill in the hospital she walks next to some parked cars and you can see the reflection of the crew and the stage lights on the sides of the vehicles. (01:12:05)
Audio problem: Rosemary eats some raw meet and throws up in her sink. We hear the sound of the running water but they neglected to over-dub the sound of her throwing up. (01:14:20)
Visible crew/equipment: In the kitchen Rosemary tells Guy that she's planning to have a party for all of their "young friends", and the shadow of the equipment can be seen on Guy's back. (01:15:05)
Visible crew/equipment: After the party Rosemary and Guy have a fight when she tells him that she wants to go to Dr. Hill for a second opinion. At the end of the scene she sits down and says "it's alive" and you can see a shadow of the crew behind her to the right moving against the wall. (01:21:25)
Audio problem: After the party Rosemary tells Guy that she wants to go to Dr. Hill for a second opinion but explains that she doesn't want to change doctors. Guy says, "I won't let you do it Ro", but if you listen closely to what he's actually saying he calls her "Rome". (01:21:25)
Continuity mistake: In their bedroom Rosemary packs her suitcase for the hospital visit, as Guy looks on. At first the window behind her is bathed in a bluish light than in the next shot the curtains are in white light. (01:23:45)
Continuity mistake: Rosemary takes a taxi cab to Hutch's funeral and the driver parks the taxi as he waits for her. The next time we see the cab it's been moved and is parked at a different angle than the first time we saw it. (01:25:00 - 01:26:05)
Continuity mistake: Rosemary takes out a Scrabble game from the book shelf to try to figure out what the anagram means. If you look at the lamp in the center of the shot you'll notice that it's behind the chess set on the table. No one goes near it but later in the scene the lamp has been moved to the right of the chess set. (01:28:25 - 01:29:40)
Continuity mistake: Rosemary takes out the Scrabble game from the book shelf and we see a statue on the table to the left of the lamp. In all of the close-up shots of her face this statue is not there, then later in the scene it returns again. (01:28:25)
Deliberate mistake: Rosemary takes out the Scrabble game, trying to figure out what the anagram means, and spills all letters onto the floor. In the next shot the title of the book "All of Them Witches" appears on the floor without her ever touching them. (01:28:30)
Continuity mistake: Rosemary takes out the Scrabble game again to try to figure out what the anagram that Hutch warns her about means. "All Of Them Witches" is spelled out and she proceeds to jumble up those letters. If you look closely in the next shot she's working on an entirely different section of the floor. (01:28:35)
Continuity mistake: As she tries to figure out the anagram, Rosemary only uses the Scrabble letters that spell out "All Of Them Witches" yet the order of the other Scrabble letters at the top of the screen change between shots. (01:28:50)
Continuity mistake: When Rosemary is playing Scrabble the angle of the shadow of her head on her collar changes between shots. (01:29:00)
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". (01:29:10)
Visible crew/equipment: When Rosemary is playing Scrabble, a crew member casts a shadow on her left. (01:29:15)
Chosen answer: It doesn't have a specific title. It was a lullaby written for the film by Krzysztof Komeda. There's a few variations of the lullaby heard throughout the film, the opening credits version is listed as "Rosemary's Baby Main Theme - Vocal."
