“Long Live the King,” the appropriate tagline on the poster for 2018’s “Black Panther,” captures this moment in history. The significance of Chadwick Boseman, who died on Friday at 43 after a four-year battle with colon cancer, to the African American and Black community is immeasurable. When representing inspirational icons such as Jackie Robinson in “42,” James Brown in “Get on Up,” or Thurgood Marshall in “Marshall,” the depth of respect is to be expected. However, two years ago, Boseman asserted himself as a beacon of hope and legacy for current and future generations, when he starred in Marvel Studios’ first Black superhero film “Black Panther.”
