Identify this haunting violin music please?

Anyone recognize this  Waltz music from the 2002 TV film
"Dr. Zhivago" with Sam Neill and Keira Knightley doing the waltz?
I recorded it from DVD, and it has Keira laughing in the middle.

I could not find an equivalent "violinstreet", let me know
if there are violin forums where such questions may be answered.

Any pointers much appreciated!

The telemovie has an original score by Ludovico Einaudi.

CD on amazon.

I can't see that the sheets have been published, though they may well have been.
