Rush was an excellent film. I'm not familiar with Formula One racing, but that movie was excellent, very underrated.
If they were to make a film based off of Brady vs Manning, I would chronicle all the years they've played each other. Brady, like Hunt, the good-looking guy, who gets the girls, the magazine spreads, yabadaba. Pey-me-alot, like Lauda, the brains, but Manning would also have a more appealing marriage, America's most-liked personality and all that. The film would focus more on Brady's personal life, because his would be more interesting. Then Manning gets chewed up by the Hawks, Brady destroys the Hawks. End movie on the NFL conspiracy to bring him down and put Manning above him. Brady and Manning could have a conversation about it at the end.
The movie will basically be about under-dog Manning, though Brady is the real under-dog, trying to beat Brady one more time before he retires. In the end, he still gets beat.
