Research for thriller opening sound

As time is approaching to the final deadline and work on the sound is being carried out, its probably for the best to listen to a few sound tracks of past/present films and openings, to help create ideas of what instruments and kind of a tempo i and my group, could/should use in making our sound in Sound Track Pro.

Below are short videos of some of the soundtracks Ive listened to;

1) 

2)

   3)

I personally believe that all the above soundtracks have some kind of an tempo or instrument that i and my group can use when creating our sound for Reap As You Sow. I personally want something upbeat and both calm at the same time, something that builds tension and also accompanies the flashes well in the opening.
