He was born on April 6, 1990, in West Chester, Pennsylvania, to Charlie and Barbara McDermott. His father is an entrepreneur who owns several health clubs. Charlie grew up with two sisters, Grace and Erin. He first attended Salesianum School in Wilmington, Delaware, before transitioning to the Pennsylvania Leadership Charter School (PALCS), a cyber school. At 16, he moved to Los Angeles to pursue a career in acting.

Career Beginnings

Charlie’s interest in acting began during his school years when teachers often allowed him to submit film projects in place of traditional assignments. His breakthrough came when he attended an open casting call for M. Night Shyamalan’s 2004 film The Village. He initially hoped to observe the director at work or gain a role as an extra but was instead cast as a boy tasked with delivering a warning to William Hurt’s character. This experience inspired him to seriously consider acting as a profession.

Acting and Film Roles

Following his debut, Charlie appeared in several television shows and films, including The Office and Private Practice. One of his most significant early film roles was in Disappearances, where he portrayed Wild Bill Bonhomme. In preparing for this demanding role, he underwent a rigorous physical training regimen that included swimming, weightlifting, chopping firewood, and working on a farm. He was cast just one week before shooting began.

In 2008, McDermott’s performance in Frozen River as T.J. Eddy earned him critical acclaim and a nomination for the Independent Spirit Award for Best Supporting Male. This recognition marked a turning point in his career and solidified his reputation as a serious actor.
