First you've got to find your protagonist, preferably with as much testosterone as possible, as per Hollywood tradition:
A) Bruce Willis as a grizzled cop who takes the law into his own hands.
B) Denzel Washington as a wily, cynical cop who has seen it all and who has too much intuition for his own good.
E) Angelina Jolie as a bad-ass crime fighter who runs around in skimpy outfits and shoots a lot of people, all with a wink and a smile and without even smudging her mascara.
F) Arnold Schwarzenegger as a guy who likes to blow up lots of stuff.
G) Will Smith as a wisecracking tough guy with a chip on his shoulder. He will speak two lines of dialogue and two lines of dialogue only:
1. "I have got to get me one of these!"
2. "Ah, hell no!"
