Injerencias en el MCU hay siempre, Ponyo, porque es como funciona la empresa. Ya te lo expliqué hace meses cuando hablamos de esto mismo. Y no solo las sufren los directores.
Por ejemplo, Patrick Doyle en el Thor de Kenneth Branagh tuvo muchas injerencias a la hora de componer la partitura (y el propio Branagh en la dirección, aunque al final salió un buen film, no notable, pero bueno) pero aún así el resultado final fue bueno y de lo mejor musicalmente del MCU. Esperemos que en esta ocasión, ya que Sam Raimi va sobrado de talento, ocurra lo mismo. Lo que no impide sentir impotencia por lo que podría haberse obtenido de no haber existido dichas injerencias.
Lo que se dijo oficialmente sobre la BSO de Thor:
Doyle made a conscious decision with Branagh to go "modern" with Thor, nobody forced him to do anything. He said it's one of the first things he and Branagh talked about.
Lo que parece ser que realmente ocurrió:
This is not what Doyle described in a video interview with Cut Filmmaking Network. They've since deleted the long interview from their site, but here what I wrote about what I heard him say:
"Listened to about 3/4th of the interview I linked above. My anticipation for his "Thor" score just went bye-bye, with him describing how the interference was like somebody standing on his shoulder, don't do this, don't do that, and, quote: "old school was a no-no"; couldn't even use trumpets until, as he said, about the last reel. And most everything had to be kept below middle C to appease, and anything above had to be really quiet."
