After Weeks of speculation. It has been confirmed by THR that Billy Dee Williams will appear as Lando Calrissian in Episode IX. Billy Dee has already canceled some convention appearances that served as a scheduling conflict with the film and sources close to the production have confirmed that Billy Dee will indeed be back.
Williams has not been in a live action Star Wars movie since Return of the Jedi all the way back in 1983 although he has always remained close to the property. He has contributed his voice to Rebels as well as Battlefront II.
There is no word on the size of Lando’s role in the film.
