'American Underdog' inspires audiences with real life rags-to-riches story of NFL star Kurt Warner
Zachary Levi plays Kurt in the film; the NFL champ gave the actor a helping hand behind-the-scenes so Levi would have all the right moves to play a quarterback.
"He came into the house very early one morning and we went out in the backyard. That was one of the first things.

"I had never really played, you know, organized football. So to get into the head of a quarterback and really understand what's going through their mind and how all those plays work and how the game at large is kind of being maneuvered was super cool. I learned so much," said Levi.
