As someone with zero interest in sport (including baseball), I love how Field of Dreams (and Bull Durham, for that matter) only pretend to be about baseball, using it as a metaphor in various ways. But Moneyball genuinely is about baseball, in the most arcane and potentially tedious of ways (statistics). For that reason, I was astonished I liked this film as much as I did (I put it on my ten favourite films about sport list a while ago). :)
