Writer/director Mike Binder said that Kevin Costner's character is an amalgamation of Detroit Tigers baseball players Denny McLain (from whom the character gets his first name) and Kirk Gibson.
In the credits, thanks are given to Universal Pictures for allowing them to use a still photo of Kevin Costner from "For the Love of the Game". The first "the" is wrong, the correct title is For Love of the Game.
Lavender "Popeye" Wolfmeyer: People don't know how to love. They bite rather than kiss. They slap rather than stroke. Maybe it's because they recognize how easy it is for love to go bad, to become suddenly impossible... unworkable, an exercise of futility. So they avoid it and seek solace in angst, and fear, and aggression, which are always there and readily available. Or maybe sometimes... they just don't have all the facts.
Denny Davies: I am so *sick* of being your bitch. I put up with your shit because I know how much *pain* you're in! But it's ENOUGH! It's a tall order for a *patient* motherfucker, and I am the furthest thing from that that you're ever going to lay eyes on.
