I'm really sorry if I post this in the wrong place

I'm trying to find the music used in this trailer, I'm pretty sure its not from the film thats advertised, I recognise it but I don't know what film its off. Plz if anyone knows what the orchestra music used in this trailer is from plz reply

all I have is this trailer with the music.
