Final answer:
In the movie Amadeus, Mozart was buried in an unmarked grave, a common practice at the time for individuals with his social and economic status.
Step-by-step explanation:
According to the movie Amadeus, which is a dramatized biography of Wolfgang Amadeus Mozart, Mozart was buried in an unmarked grave. This portrayal is based on historical belief that Mozart, despite his genius in music, was not given a lavish burial and was buried in a common grave, which was a standard practice at the time for people in his financial and social standing. This common type of grave would not have a monument indicating who was buried there, hence the term 'unmarked grave.'
