Chadwick Boseman died a year ago Saturday, after a four-year-long battle with colon cancer. The "Black Panther" star was 43. Boseman took on monumental roles in his film career portraying historic figures like Jackie Robinson, James Brown and Thurgood Marshall and also took on a groundbreaking role as Marvel's Black superhero T'Challa. Co-stars and friends of the actor shared touching words of his memory. Lupita Nyong'o who starred alongside Boseman as his "Black Panther" love interest Nakia dedicated an Instagram post to her late co-star. "I did not know that I could miss both his laughter and his silence in equal measure. I do. I do...," she wrote in a caption for a photo of the two of them laughing together. "One year after his passing, the memory of @chadwickboseman remains this alive in me." 📸 Victoria Will, @apnews
