Sure, it’s a nice story, interesting concept, and a legitimately good, plausible idea. But it would have been an even better one, had the real, actual results amounted to any actual success.
SPOILER ALERT: the two Indian guys that Million Dollar Arm is about didn’t amount to anything in professional baseball. Neither of them advanced beyond the low minor leagues, and for all intents and purposes are no longer pitching professionally; Dinesh Patel flamed out in 2010, and Rinku Singh may or may not still be pitching, but not for anyone in the United States, and hasn’t since 2012.
Sure, baseball is a beautiful and wonderful game, and it is often hard to not romanticize the analogies and the metaphors that the game provides, which makes it easy for there to be a demand to make movies about the sport. Regardless, that kind of realistic information isn’t going to stop Hollywood, or Disney from making a film to exploit the story of how such results came to fruition, without actually getting to that part.
