He was cast as Miles Socorro, a human teenager living amongst Na'vis on Pandora. The nature of Champion's role meant that he had to film all his scenes twice, once as a reference for his co-stars, including Sam Worthington, Zoe Saldaña and Sigourney Weaver, and another to actually film the actor in live-action; his work involved two years of performance capture on a soundstage, followed by two and a half years of filming the same scenes in live-action in New Zealand. He learned freediving and scuba diving for scenes that were filmed underwater. After five years of production, the film was released in 2022, after Champion turned 18.
