ComingSoon.net has a small article about the film, the trailer, and a bunch of stills from behind-the-scenes/ promo shots. It looks like this could be really epic!
If you want to just see the trailer, then look no further!
This could be interesting, since:
"Cusack has trained in kickboxing for over 20 years, under former world kickboxing champion Benny Urquidez. He began training under Urquidez in preparation for his role in Say Anything... and currently holds the rank of a level 6 black belt in Urquidez's Ukidokan Kickboxing system."

This means we could have the potential for some good fight sequences between him and Chan. Time will tell!
