Canadian actors Stephan James and his brother Shamier Anderson launched the project as a way to connect diverse actors with movie industry leaders. ET Canada caught up with them and another set of famous brothers, “Avengers: Endgame” directors Anthony and Joe Russo, to chat all about the exciting event.
