No big thing, but how hard would it have been to get it right?In the movie “42,” Brooklyn’s Gene Hermanski is seen batting right-handed. He batted left-handed. Bucs’ pitcher Fritz Ostermueller throws right-handed; he was a lefty. Leo Durocher wasn’t suspended for carrying on with women, but with gamblers.The 1947 scene in which Jackie Robinson is spiked at first by the Cardinals’ Enos Slaughter shows Hugh Casey to be the Dodgers’ pitcher. It was Ralph Branca — no small fact. (Running to cover first, Branca told Robinson he would retaliate in Slaughter’s next at-bat. Robinson insisted that he not — Branca was pitching a perfect game. It ended a one-hitter — Slaughter’s grounder between Robinson and Eddie Stanky in the eighth.)In the dramatic scene (and movie poster) in which Pee Wee Reese drapes his arm around Robinson’s shoulder, they appear with “Dodgers” across the fronts of their shirts, their home uniforms. But they were in Cincinnati, wearing their grays, “Brooklyn” across the front.And neither Robinson nor any other big leaguer of that time stood posing after hitting a home run.
