Anton Ivanovich Is Angry (Russian: Антон Иванович сердится) is a 1941[1] Soviet musical comedy film directed by Aleksandr Ivanovsky.
His disdain for contemporary music strains his relationships, especially when he learns that his daughter Sima is being courted by Mukhin, a composer of "frivolous" foxtrots for operettas.
Voronov, who initially forbade Sima from performing, learns of her involvement from his tenant, the inept composer Kerosinov, who inadvertently reveals her secret.
That night, he dreams of his idol, Johann Sebastian Bach, who humorously confesses a secret longing to compose operettas instead of the chorales he is famed for.
Embracing a newfound openness, he participates as an organist in the premiere of Mukhin's new oratorio, a celebratory work dedicated to the victory of labor and socialism, symbolizing the bridging of generational and artistic divides.
