The music in the trailers for this one is contemporary, understandable, I guess. Getting younger people to come see a period piece about 1940s baseball when Jackie Robinson integrated America’s Pastime,” is going to be a hard sell to the hip hop generation. The Big Band Era “Did You See Jackie Robinson Hit that Ball?” wouldn’t help.

Harrison Ford as the fast-talking, principled but hustling Branch Rickey could be interesting. Has Ford ever played a fast talker? Not that I can recall.

Not that accuracy has to be taken to that degree. Hope for a breakout performance by Chadwick Boseman (Jackie had a mousy, non-threatening voice). Get the basic facts right, show the racial hostility within the game and among the white American fanbase, tap into the icon Jackie became — instantly — to black America, and make the baseball convincing.

Those are my fondest hopes for Brian Helgeland’s “42.” The screenwriter (“Man on Fire,” “Conspiracy Theory”) turned director (“A Knight’s Tale”) succeeded where Spike and Denzel, who wanted to do a version of this story for years, could not.
