Eleven-year-old Dexter Sol Ansell speaks about his acting career with the poise of someone much older, discussing character motivation, directors he admires, and the challenges of filming in cold water. He has appeared in several films and television shows, including "A Knight of the Seven Kingdoms," "The Hunger Games: The Ballad of Songbirds & Snakes," and "Robin and the Hoods." His latest film, "500 Miles," sees him playing Charlie, the younger brother of Finn, portrayed by Roman Griffin Davis, on a 500-mile journey to find their estranged grandfather, played by Bill Nighy, with Maisie Williams also appearing in the film. Dexter began acting at a very young age, starting with the British soap opera "Emmerdale" when he was just four. He recalls one of his earliest memories of acting as being when he held a gun in a scene at that young age. Filming for "500 Miles" included challenging conditions, such as filming in the Irish Sea in November, which was so cold that some takes could only last seconds before he turned blue. He also recounts being stung by a wasp while covered in fake vomit during filming on a boat. Dexter describes acting as part of his life, stating that it feels more like fun than work. He has a simple approach to getting into character, saying that when the director says "action," he forgets everything in real life and becomes the character. He also mentions that he has a ritual for auditions, which involves listening to the song "Eye of the Tiger." Dexter has a close relationship with his family, and he often consults his mother for opinions on characters from "Game of Thrones." He also enjoys spending time with his friends and doing "kid stuff," such as fishing with his dad and going to arcades. Despite his busy schedule, Dexter still finds time for these activities. He has a dream role that would involve a character who goes "from nothing to all of this," similar to the character in "Billy Elliot." He also hopes to direct and has begun writing. Dexter views adults on film sets as just friends, not different from his peers. He is currently working on the first season of "A Knight of the Seven Kingdoms" and is preparing for the release of "500 Miles," which is available on platforms like Apple TV and Amazon Prime Video.
