42 is a 2013 American biographical sports film written and directed by Brian Helgeland. The plot follows 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.

The project was announced in June 2011, with principal photography taking place in Macon, Georgia and Atlanta Film Studios Paulding County in Hiram as well as in Alabama and Chattanooga, Tennessee.

42 was theatrically released in North America on April 12, 2013. The film received generally positive reviews from critics, who praised the performances of Boseman and Ford, and it grossed $97.5 million on a production budget of $31–40 million.
