Even though the movie is fundamentally about statistical analysis, the attempts at humanizing the story largely work. Beane is presented as somewhat quirky (he never watches a game in person, preferring instead to work out), and he is also portrayed as regretting his decision to enter the majors instead of going to college because he ended up being a wash even though he was considered one of the best prospects of his time. Beane eventually warms up to his players throughout the movie, taking time to get to know them, to coach them (with the help of statistical analysis, of course). It helps that Beane is played by Brad Pitt, who brings a wonderful human warmness and complexity to this role.
Brand is played by Jonah Hill, he does an excellent job of playing the shy, nerdish stats geek. Beane encourages Brand to become more involved with the players, and Hill gets the initial awkwardness of Brand’s antisocial tendencies just right. Hill also brings some depth to Brand, in subtly portraying him as a bit of an overachiever who often seems embarrassed by his ambition and passion for stats and baseball.
The rest is here.
