Black Panther star Chadwick Boseman has spoken for the first time about meeting Denzel Washington, an actor who once served as his secret benefactor.
"I got to tell you something," Boseman recalled telling the Malcolm X star on 13 February. "You paid for me to go to school."
"Oh, so that's why I'm here - you owe me money!" came Washington's light-hearted response. "I came to collect!"
Black Panther, in which Boseman pays an African king who moonlights as a crime-fighter, has made more than $760m ($551m) worldwide.
The film has been widely praised for utilising a predominantly black cast and for addressing such issues as racism, colonialism and slavery.
