Marvel never asked actor Richard Madden to dye his hair blond or change his accent for his role in Eternals. Madden plays Ikaris, who has traditionally had blonde hair in his comic-book incarnation. Created by Jack Kirby in 1976, Ikaris is an Eternal, created by the Celestials thousands of years ago, gifted with superhuman abilities that are meant to protect and guide humanity. Ikaris’ earliest appearance shows him with longish blonde locks and he is fitted with a blue-and-red costume with three circular-shaped designs on his chest.
Eternals is directed by Academy Award Winner Chloé Zhao and stars Madden, Gemma Chan, Angelina Jolie, Salma Hayek, Kumail Nanjiani,
