The cast of Black Panther do some unusual marketing for the film by trying their hand at a fear box. Marvel didn’t always have the Black Panther rights, as he was one of many characters they sold off and had to buy back after declaring bankruptcy in the mid-1990s. The company’s prospects have since turned around in a huge way, and a solo movie starring T’Challa is now a reality and starting its international rollout, ahead of its domestic release.
