Aquí os dejo lo que comentó sobre la salida de Marianelli:
"Sadly Marianelli had to go. Who to blame? The corporate body of Warner Brothers. They'd make remarks like "your score is too European". The producers obviously want a lighter, funnier film and thought his score was too dark. Director still supported him. But ultimately with these big studio pictures, the studio has the final say. So bastards really.
Apparently the guy who works on this picture said he wasn't all that surprised, since they had pretty much said it might happen for the last 4 months.
But it doesn't excuse them having worked directly with him, saying they were happy with everything and then turning on him after the screening. If they were unhappy with the musical direction, they should have told him sooner. If only to give the next guy a half chance of writing a decent replacement score.
As regards score, it's like an old school score really. Orchestral, grand, heavy use of brass. A bit more straightforward harmonically than Brothers Grimm. He simplified it quite significantly after the first preview. In an effort to make it less European. Sadly it was never recorded.
As for Marianelli, he's pretty pissed off.
I don't envy Powell really, as he has a hell of a mountain to climb because the recording sessions are in 5 weeks time!"
