context: Chiwetel Ejiofor was officially chosen on November 1, 2017 for the role of Scar for the CGI live action remake, "The Lion King" (2019) directed by Jon Favreau, as he had impressed him after watching his antagonistic performance as Baron Mordo in the Marvel film "Doctor Strange" (2016). Ejiofor said that "especially with Scar, whether it's a vocal quality that allows for a certain confidence or a certain aggression, to always know that at the end of it you’re playing somebody who has the capacity to turn everything on its head in a split second with outrageous acts of violence - that can completely change the temperature of a scene". Favreau said of casting Ejiofor, "[He] is just a fantastic actor, who brings us a bit of the mid-Atlantic cadence and a new take on the character. He brings that feeling of a Shakespearean villain to bear because of his background as an actor. It's wonderful when you have somebody as experienced and seasoned as Chiwetel; he just breathes such wonderful life into this character." When Jeremy Irons was interviewed on Larry King Now on November 30, 2016, he expressed interest in reprising the role.
