I am looking to compile my own playlist of themes from movies with Russian influence (which must include a chorus section).

Some examples:

Hymn to The Hunt for Red October
Basil Poledouris - Hymn To Red October - YouTube (http://www.youtube.com/watch?v=rPsL2WVhFCc)

Song of the Plains (Used in Castaway)
Soviet Army Chorus & Band - Song of the plains - YouTube (http://www.youtube.com/watch?v=5hliuEte028)

Kremlin with Anticipation (M:I 4)
Mission: Impossible Ghost Protocol Soundtrack - Kremlin With Anticipation - YouTube (http://www.youtube.com/watch?v=SXSo1JhWE68)

Between these three tracks, you can see what I am looking for. Any recommendations or suggestions would be highly appreciated.

Thanks.

Alexander Nevsky for sure: Prokofiev - Alexander Nevsky 4 Arise, Ye Russian People - YouTube (http://www.youtube.com/watch?v=5F6e9mI1bGU)

Also the Mask of the Phantasm theme: Batman Mask of The Phantasm Theme - YouTube (http://www.youtube.com/watch?v=TOSS-ZFDMo4)
There is a similarity with the Hymn of the Red October, yet that doesn't change a bit of the fondness i have with this score in particular.

Thank you for taking the time to respond. I will definitely look into your suggestions.
