Does my opening develop or challenge current film openings?

Ive decided to start of my short film opening with an action scene which is what I believe my audience would want to see. This idea of an action scene at the start comes from films like Lord of the Rings Fellowship of the Ring also Saving Private Ryan. Although my is a bit different because I've set mine to be like a trailer.

Inspiration for sequence of the trailer :http://www.youtube.com/watch?v=lalm_kkczVM

I set mine to be as a trailer so that not only does it address the audience but it gives the viewer a hint that trouble might be on its way.
