The reason for the poor cooperation at the beginning was that these people had not performed officially for 30 years. You can notice that Andre picked these people out from funeral bands, gypsy camps and AV dubbing studios. These people came to Paris with various purposes in the first place. Especially since Victor and his son are basically here to do business (carrying a box of caviar). They didn't show up until they saw a text message from the Jewish father and son saying, "Come back for Leya." Therefore, everything was out of tune at first, but because the piece was a concerto in D major, there was a long violin solo. When these people heard Anna's performance, they thought of Léa back then, so they regained the original feeling. I think this This is what the film wants to convey. In fact, the final performance should not be viewed as part of the plot of the movie, but as a symbolic performance for the integrity of the film's narrative. In this section, the director further revealed the previous suspense, and at the same time pointed out the future fate of these people, completing the climax of the dramatic conflict of the entire play, and ending in the climax. I personally think this arrangement is very exciting. In addition, I would like to praise the exquisite arrangement of various elements in this film. You can see that Andrei's greatest effort was to come up with the idea of ??performing in Paris instead of the Moscow Symphony Orchestra. Everything else happened basically by chance. I went to see the leader of the Galileov team. The reason why he agreed was to speak at the Communist Party Congress in Paris. The passport was issued by a gypsy, and the sponsorship was obtained by a natural gas boss who happened to be attending the wedding (probably an extra at the wedding, although it was not stated clearly). Paris agreed because they were financially strapped. This kind of coincidence happened because these people had already given up on the music path. But at the end of the film, these people who had given up music long ago regained their lost dreams by virtue of this opportunity. Personally, I think this is the most touching part of the final scene, and it’s also why Galileev finally lamented that God really exists.

One more thing, there are actually three attempts to express this "miracle" in the final performance. The first is a direct expression from Galileov's mouth, and the second is a kiss from the director of the Paris Theater His assistant, this is a kind of joking magic. The last part is that Victor said "Amen" after the performance. He is a Jew. In fact, what he said was not Amen, but the Jewish way of praying.

Finally, I feel like Judaism has been hacked from beginning to end. Earlier, Sasha told Victor that there are synagogues everywhere in Paris, and even the funeral of a cardinal was hacked. You see, Victor’s son was entrusted to Moses, who is the great God who saves people in the Old Testament (Judaism does not recognize the New Testament). It was Moses who came up with the idea of ??buying a mobile phone when he went to Paris this time. Not only did he save his father, but he also became the leader of these people. The key to the re-performance is actually the logical chain of the various nodes of the story that Moses appeared in just a few times to connect together.
