James Allen McCune was born as the youngest of three children in Atlanta, Georgia to loving parents Charlotte and Loren McCune. His early life was marked by a strong foundation in the arts, as he began acting at the tender age of 17 in his high school's esteemed drama club, "ECHO Stage". This initial foray into the world of theatre would lay the groundwork for a lifelong passion for the performing arts, as he went on to hone his craft through musical theatre in Atlanta before transitioning into the realms of film and television.
As his talents continued to flourish, McCune would land a pivotal role as "Jimmy" in the second season of AMC's critically acclaimed series, The Walking Dead. This breakthrough performance would ultimately prompt him to relocate to Los Angeles, where he would further pursue his dual passions as a musician and actor. His subsequent roles would showcase his impressive range, including "Matty" in Showtime's gritty drama Shameless, and "James" in Adam Wingard's suspenseful horror film, Blair Witch.
