Continuity: In the scene when the captain demonstrates the whistle signals for each of the children, Maria calls out to the captain with a whistle blow, asking what his signal would be. The captain stops walking and makes almost a full body turn to look back at Maria. But in the next shot he is shown to have turned only his head to look over his shoulder and says, "You may call me, Captain", and walks out straight ahead.

Continuity: In the scene in which Maria and the children are in a carriage singing Do-Re-Mi around Salzburg, at one point (when she is sitting facing the kids) she passes a shop that is painted in a very distinct color and with a distinct sign (it begins with an F: Frachts?), and a few seconds later, as she turns around to sit forward in the carriage, they pass the same store.

Revealing: In the scene where Captain von Trapp takes a Nazi flag and tears it in two pieces you can see him searching for the correct place to tear. If you look closely you will see that a small incision has been made already so it tears more easily.

Revealing: When Gretl runs up to Uncle Max saying, "Can we really keep the puppet show, Uncle Max?", you can see Marta in the background begin her cue too soon as she starts to run up to Uncle Max in the middle of Gretl's line, but quickly stops herself. Then after Gretl finishes her line, Marta carries on and runs up to Uncle Max with the rest of the children and says her line.

Continuity: Part way through the "Do-Re-Mi" sequence, when Maria and the children are walking down the steps overlooking Salzburg, the sun changes direction. At first it's behind them, so their faces are in the shade. Then suddenly the light is in front of them, and their shadows have changed direction too.

Continuity: Nicholas Hammond (Friedrich) was not a natural blond. The first scene to be shot involving him was the "My Favourite Things" scene and you can see that his hair is pale auburn. After this scene was shot, the directors thought that he would look better if his hair were lighter, so they applied an early form of bleaching agent to his hair. In scenes which were shot after this (notably the children's first entrance to meet Maria which occurs before the "Favourite Things" scene) his hair is very, VERY blond, almost white. In fact, if you scrutinise his hair closely throughout the film, it is a different colour in practically every scene, depending on when the scene was shot and how much of the bleaching agent had been applied.

Continuity: Christopher Plummer throws down the drape the kids used for clothing on the ground. Then he walks away and there's a clear shot of the ground and the drape has vanished.

Continuity: When the children are singing for the Baroness, the Captain joins them and enters the room. In this wide shot, we see Liesl only begin to put down the guitar. In the close up shot of the children, however, the guitar is almost all the way down.

Audio problem: During the song "The Lonely Goatherd," Maria sings, "Men drinking beer with the foam afloat," Gretl blows foam from the cups into Maria's face, and she coughs. You can see that Julie Andrew's mouth is not at all in sync with the coughing on the recording.

Continuity: Just before the Captain is about to sing Eidelweiss to the children, Max, Maria and the Baroness, the Baroness says to Max "Well why didn't you tell me, I could have brought along my harmonica." She has a glass of champagne in her hand and is about to take a sip but the camera cuts back to the Captain starting to sing and the glass is back resting in her hand.

Continuity: After the boat overturns on the lake, and Maria is standing on the terrace arguing with the Captain, her wet hair style changes several times.

Continuity: In the scene right before the song "Sixteen Going On Seventeen", sung by Liesl and Maria, Liesl looks down and says a line ending with "...and he stops loving you." and then looks up. The shot from behind shows her looking up again.

Continuity: During "Do-Re-Mi" Maria's hair is blowing in the wind in the long shots but is perfectly combed in the closeups.

Audio problem: During the bedroom storm scene singing "My Favorite Things", you can see Marta sitting next to Frauline Maria and she gets wrapped up in the moment of Maria singing and mouthes "...feel so bad" and she's not supposed to be singing.

Continuity: After "How Do You Solve a Problem Like Maria?" a nun is shown walking Maria to Mother Abess's office. She says, "You may go in now, Maria", places her hand on Maria's shoulder, and then walks away. In the next shot that's viewing them from inside the office, the nun is seen repeating the same action.

Continuity: When Maria leaves the Abbey to go to the Von Trapps, she walks for a ways, then takes what appears to be a rather long bus ride. This shows a fair amount of distance between the Von Trapps' house and the Abbey. Yet, when Maria snuck out to return to the Abbey during the party, it was night, and she had no ride waiting. Later, after the Captain tells the children he will marry the Baroness, they walk to and from the Abbey in an unsuccessful attempt to see Maria, and in an apparently short amount of time. From the initial bus ride, the Abbey was simply too far away for those walks to be believable.

Continuity: In the scene right before "Edelweiss", the Captain is asked by the children and Maria to play something on the guitar. The Captain is holding a glass in his right hand and then proceeds to raise his left hand in a negative gesture. The shot changes, and the glass is now in his left hand- with his right hand raised to gesture.

Factual error: When the Von Trapp family is hiding in the Abbey to avoid the Nazis, they are hiding behind some headstones. In reality, these headstones are flush against the wall and no one would be able to fit behind them.

Continuity: At the party Captain von Trapp puts on for the baroness, there is a scene where the guests are being greeted by Captain von Trapp and the Baroness inside the doorway of the house. When Heir Zeller is greeted and he looks ahead you can see a lady with brown hair in a pale blue dress being greeted in the background and then looking over her left shoulder. It then cuts to a scene where Heir Zeller has moved further into the house away from Captain von Trapp and the Baroness, and you can see she is greeted a second time and again looks over her left shoulder.

Continuity: When the Captain is asked to allow the children to sing in the festival by Max, he protests. He crosses to a table and says "Max." and picks up a glass. The shot changes, he says "My children do not sing in public", and there is now a bottle in his hand.
