Wesley Kimmel is the one receiving a brand new Mandalorian helmet in the first episode of "The Mandalorian" Season 3. And that last name is no coincidence. He is, indeed, the nephew of late-night talk show host Jimmy Kimmel, but he's quickly becoming an actor in his own right.
His resume is building up nicely. While he initially appeared periodically on episodes of "Jimmy Kimmel Live!," he's gone on to pop up in various films and TV shows, including "The Rookie" and "Good Girls." However, he appears to be carving out a nice niche for himself on Disney+. He stars as the Commercial Boy in a few episodes of "WandaVision," and he played a Tusken Kid on the first three episodes of "The Book of Boba Fett." He must've made a good impression on somebody to come right around and rejoin "Star Wars" for "Chapter 17" of "The Mandalorian."
Most recently, Kimmel could be found playing Jack in the Netflix original film "Your Place or Mine," starring Reese Witherspoon and Ashton Kutcher. It's also been confirmed that he'll appear in the upcoming Amazon Prime Video movie "Red One," so he's certainly keeping busy these days.
