Barack and Michelle Obama were at America's National Portrait Gallery to present two new additions to the collection, painted by Amy Sherald and Kehinde Wiley. The presidential profile also features in a book by official White House photographer Pete Souza, who tells our reporters about his favourite snap of Obama. Also on the show, we check out the new Marvel movie "Black Panther" as it gets a warm reception at its premiere in Nigeria, and Palestinian director Annemarie Jacir tells us about turning family ties into cinematic drama in prodigal son story "Wajib".
