Continuity mistake: When the children and Baroness Schrader are playing the game with the ball, they all have numbers which they say as they bounce the ball to one another. These numbers then change once they start throwing the ball (Friedrich starts as 4 and becomes 5, the Baroness starts as 5 and becomes 6, etc.).
Other mistake: When Maria and the children are having a picnic on the hilltop, Gretl and Leisl appear to be playing go fish. If you look carefully, Gretl takes three turns in a row.
Factual error: When singing "Do-Re-Mi", Maria is playing a Goya guitar. Goya brand guitars were not invented until the mid-1950s, a good ten years after this takes place.
Continuity mistake: When the kids ask a nun about Maria, they stand apart in the angle from behind, but are closer together in the front one.
Sacha
Continuity mistake: In the first scene where Maria is singing "The Sound of Music" there are two different camera shots; in the long shot the grass is a yellowy colour and in the close up the grass is suddenly green. (This has been fixed on the 40th anniversary DVD.)
Continuity mistake: When Maria sings "and then I don't feel so bad", Marta's ponytail swaps positions for a brief moment.
SachaContinuity mistake: When the Edelweiss song ends, Max starts to talk and the Baroness has nothing in her mouth. A frame later, from a different angle, she has her hand up holding a cigarette.
SachaContinuity mistake: Mother Abbess is singing next to a window, but when the angle changes the window is gone and there's just a wall.
SachaContinuity mistake: After the "Do re mi " song the Capt.'s car makes a right turn and drives through a road. In the close-up it's several meters behind passing by the same trees again.
SachaContinuity mistake: While Maria prays for the kids' new mother and Leisel enters through the window, the coat lying on the chair changes the way it's folded between angles.
SachaContinuity mistake: While the kids are watching the people waltzing, Gretl stands facing the room, but a frame later she's leaning sideways against the walls.
SachaContinuity mistake: During the puppet show Marta changes the backdrop but from a different angle and for a very brief moment, it's the previous one, with a sky instead of a castle.
SachaContinuity mistake: Before the Edelweiss song, the Baroness takes a glass to her lips, but a a frame later her hand is down.
SachaContinuity mistake: When Rolf brings a telegram he extends his arm and immediately after, he lowers it. A frame later it's extended and he is lowering again.
SachaContinuity mistake: While Liesel tells the nun that she wants to visit Maria, Friedrich and Kurt keep changing positions between shots.
SachaContinuity mistake: When the ballroom dance starts, the Capt. and the Baroness greet the guests. The number of people walking down the stairs behind them increase, decrease or simply disappear between shots.
SachaAudio problem: When Georg playfully taps Max's cheek, we hear 3 taps but Georg only taps twice.
Continuity mistake: When the captain sings for the first time and hugs the children, Gretl is under his left arm. In the next shot, he raises his arm and she is nowhere to be seen. Then, when Maria motions for Gretl to give the Baroness the edelweiss, she is back under his arm.
