Fun story about Hidden Figures. About 30 years or so ago, I interviewed a young actor named Olek Krupa who had just emigrated from the Soviet Union. He didn't speak English very clearly, but he was starring in a production of Dracula. You couldn't understand him from the stage, but it didn't much matter. He projected an almost animal sexuality that you understand why Lucy and Mina and most of the audience were hypnotized by him.
He's much older in Hidden Figures, where he plays an engineer who encourages Janelle Monae's character, but at least I could understand his English.
