Audio problem: During the bedroom storm scene singing "My Favorite Things", Marta is sitting next to Fräulein Maria and she gets wrapped up in the moment of Maria singing and mouths "feel so bad" - she's not supposed to be singing.
Audio problem: During the song "The Lonely Goatherd," Maria sings, "Men drinking beer with the foam afloat," Marta blows foam from the cups into Maria's face, and she coughs. You can see that Julie Andrews' mouth is not at all in sync with the coughing on the recording.
Audio problem: When Georg playfully taps Max's cheek, we hear 3 taps but Georg only taps twice.
Answer: In the film, the Mother Abess explains to Maria that the Captain Von Trapp's wife died "several years" ago. This is commonly misheard by viewers as "seven years." In reality, the actual mother of the Von Trapp children was Agathe Whitehead, who died of scarlet fever in 1922, just four years before Maria came to the Von Trapp home, initially as a tutor (not a governess) in 1926.
