Okay the MI:4 trailer just went from looks badass to completely off the hook badass. Seriously smoking. Sucks the odds of this script showing up are slim to non-existent.
Reason that trailer had such an impact was because he cut shots/the gunshots/climax shots to the percussion of that Eminem track in the 1st half -- which has a double time rhythm. Great technique. Oliver Stone did it for the intro credits to "Salvador" (his 1st film).
