ITV Wuthering Heights trailer music

[boingboing]

Hi everyone, just seen a short trailer for ITVs upcoming production of Wuthering Heights with a short piece of volin music playing. Sort of recognise the tune but can't quite place it, any ideas? I've googled but all I get is the longer trailer with different music which I am pretty sure is from the soundtrack to the Pacino/Crowe film The Insider (my all time favourite film). It's the shorter violin piece I'm looking for, any help much appreciated thanks!

If it's the short trailer with Sarah Lancashire in, the music is Iguaza by Gutavo Santaolalla
