To call Bobby Kotick's appearance in Moneyball a cameo is a bit of a misnomer. The Activision boss has two significant scenes in the sports flick and plenty of lines as Stephen Schott, the former co-owner of the Oakland Athletics. It's not to say Kotick plays much of a character, but he doesn't have to. He simply has to be what he is in real life.
To back up a bit, Kotick ended up in the film thanks to his friendship with its director, Bennett Miller. While based on a true story, Moneyball had to be streamlined somewhat for cinema, and in so doing, the Oakland Athletics' owner partnership of Schott and Ken Hofmann needed to be consolidated into a single guy. That became Schott, a successful real estate developer who, evidently, favors corded cashmere sweaters.
