I really like your photo and especially her expression, it's a great shot! I also agree with Windrider that it really depends on what type of movie you are going for since there are so many different styles.
However, for my personal taste, I think that a lot of current movies have a much more saturated style to them and are generally very heavy on the complementary colors of red-orange and blue-green in order to not only complement itself, but also to be able to saturate skin tones as much as possible while still keeping them realistic.
Here is my take on your photo, if you want me to take it down, let me know and I'll be glad to:
I copied the original and changed the duplicate layer to multiply and changed the opacity down to 15% just to add a bit more depth and contrast.
Then I made three different color balance layers and played with the levels boosting the highlights on each to up about 25 towards red and down about 7 towards magenta and taking the shadows in the opposite way about plus 15 each towards green and also up towards blue and down towards cyan and then just played with the midtones a bit until I liked how it looked.
I'm sure there are a lot of different ways to get this effect, but that's how I did it.
