Grant Feely was born in Brunswick, Georgia in October 15, 2011. At seven years old, he watched the show Stranger Things and was interested in the behind-the-scenes material. He wanted to be a part of that world, so he decided to become an actor. Star Wars: The Mandalorian was the only Star Wars content that Feely had seen. In April, 2021, Feely's agent sent him the audition for a role. He then filmed an audition for "Boy - Untitled Disney+ Series," not knowing the role was for the Star Wars: Obi-Wan Kenobi television series, and he did not think anything of it. A week later, he had an hour-long Zoom callback with Carmen Cuba, the casting director for Obi-Wan Kenobi. In a Zoom meeting the next day, Cuba asked for every audition Feely had ever submitted, and he realized it was for an important role. In early June, he had a director's callback with director Deborah Chow. When he was in Hawaii during the end of June, he was asked if he could come to Los Angeles. He was not able to go, so they flew him to LA to do an in-person audition with Chow. In early July, Chow called Feely to offer him the role of Luke Skywalker. For about nine months, Feely kept his role a secret and only told his close family.
