Closing Interview Excerpt with Spire Magazine:[]
"We just finished up "The Expendables" with Jason Statham, Mickey Rourke, Stallone, Randy Couture, Steve Austin and those guys… which isn’t really a martial arts film, but was a lot of fun. And we got to do some movie type MMA in it, which was really cool. Other then that we have "The Mechanic" which is another movie which Jason Statham, which is going to be pretty interesting... but that’s it for right now."
