Inspiraton from Inside Man

I tried my best to find just the opening scene but it doesnt exsist seperately and without enfringing the films copyright and legal use i just decided to post the trailer. Well basically i remember watching Inside Man almost a year ago because the way it began was very unusual, in a sense that it clealy state the Who,What,Where,When and then leaves the How out so it can be told during the movie. This is what came to mind when i was told we had to shoot the opening to a thriller.
