The Sundance Film Festival is part of the DNA of “Judas and the Black Messiah” — the festival is where writer, producer and director Shaka King first pitched his Fred Hampton film to Ryan Coogler. Plus, Sundance is where stars Daniel Kaluuya and Lakeith Stanfield’s first collaboration “Get Out,” premiered three years ago. While there’s no in person festival this year, due to the ongoing pandemic, the debut of “Judas and the Black Messiah” is still set to be a cultural moment.
