42 is a 2013 American biographical sports drama film produced by Legendary Pictures and distributed by Warner Bros. Pictures. Written and directed by Brian Helgeland, 42 is based on baseball player Jackie Robinson, the first black athlete to play in Major League Baseball (MLB) during the modern era. The title of the film is a reference to Robinson's jersey number, which was universally retired across all MLB teams in 1997. The ensemble cast includes Chadwick Boseman as Robinson, alongside Harrison Ford, Nicole Beharie, Christopher Meloni, André Holland, Lucas Black, Hamish Linklater, and Ryan Merriman in supporting roles.

Spike Lee initially planned to direct a biopic in 1995 with Turner Pictures, but the project fell apart due to creative differences and later financial challenges. In 2011, Legendary Pictures took over, collaborating with Robinson's widow, Rachel Robinson, to ensure authenticity. Boseman, cast as Robinson in his breakout role, impressed Helgeland with his athleticism and emotional depth during auditions. Boseman trained to replicate Robinson's mannerisms and connected with Rachel for character insights. Filming began in 2012 across locations like Chattanooga, Tennessee, and Birmingham, Alabama, with Engel Stadium standing in for the Brooklyn Dodgers' Ebbets Field. The production used digital recreations of historic stadiums and involved local extras.

42 was screened at the White House and premiered at TCL Chinese Theatre in Los Angeles before it was released on April 12, 2013, by Warner Bros. Its release was three days before Jackie Robinson Day, celebrated annually on April 15. The film received generally positive reviews from critics, with praise centered on Boseman's heartfelt portrayal and Ford's stylized performance. 42 earned $97.5 million worldwide against a $40 million budget, including a record-breaking $27.5 million opening for a baseball film.
