As an activist himself, Robinson would likely have been disappointed by a film that ignored the centrality of the broader civil rights struggle.
That story has been told in two outstanding books, Jules Tygiel’s Baseball’s Great Experiment (1983) and Chris Lamb’s Conspiracy of Silence: Sportswriters and the Long Campaign to Desegregate Baseball (2012). As they recount, Rickey’s plan came after more than a decade of effort by black and left-wing journalists and activists to desegregate the national pastime. Beginning in the 1930s, the Negro press, civil rights groups, the Communist Party, progressive white activists, and radical politicians waged a sustained campaign to integrate baseball. It was part of a broader movement to eliminate discrimination in housing, jobs, and other sectors of society. It included protests against segregation within the military, mobilizing for a federal anti-lynching law, marches to open up defense jobs to blacks during World War II, and boycotts against stores that refused to hire African Americans under the banner "don’t shop where you can’t work." The movement accelerated after the war, when returning black veterans expected that America would open up opportunities for African Americans.
