David Fincher directs the life-long journey of pro football players LaDainian Tomlinson and Troy Polamalu as their destinies collide in an NFL football game. PRETTY HILLARIOUS: Now I present the short play: "Nike Pitches This Ad to LaDainian Tomlinson." SCENE: A conference room. Nike: "We have a great new ad concept to share with you, LT. Troy Polamalu is on board with it, too." Tomlinson: "Great. I love Troy. Let me hear it." Nike: "It will show both of you from birth to present day, cutting back and forth between the two of you running through the house as kids, playing biddy basketball and football, playing in college, then finally meeting each other head-on in the NFL. And the whole thing is set to some pretty cool music." Tomlinson: "Sounds awesome. I'm in." Nike: "Oh, one thing. The ad concludes with Polamalu stopping you dead in your tracks, even though you have a full head of steam going." Tomlinson: "Ummmm … " Nike: "Yeah. Tough break." Tomlinson: "Do I get replaced by Darren Sproles in the next ad?" Nike: "No." Tomlinson: "OK, cool. I'll do it." (http://sports.espn.go.com/espn/page2/story?page=gallo/081013&sportCat=nfl)
