Actor Chadwick Boseman, who plays Jackie Robinson in the new movie "42," made a return trip to the District on Monday night for a screening of the film at the Smithsonian National Museum of American History. Boseman was joined by John Gray, director of the National Museum of American History, and Lonnie G. Bunch III, director of the Smithsonian's National Museum of African American History and Culture, which is expected to open on the National Mall in 2015. Earlier this month, Boseman held court at the White House with first lady Michelle Obama, actor Harrison Ford and Jackie Robinson's widow, Rachel Robinson.
