Jaeden Martell was born in Philadelphia, Pennsylvania. In 2011, at the age of eight, he moved with his mother across the country to Los Angeles. He never expected that this adventure would lead him into a life of acting. Without any acting classes or training and shortly after arriving in Los Angeles, Jaeden began starring in a number of commercials. At the age of nine he made his big screen debut with a small role playing a young Chris Evans in “Playing it Cool.” In the summer of 2013, Jaeden made his way back to the East coast to film St. Vincent (2014), written and directed by Ted Melfi. He was lucky enough to star in the film with legendary actors Bill Murray, Melissa McCarthy, and Naomi Watts. Shortly thereafter he landed roles in Cameron Crowe’s “Aloha” and Jeff Nichols’ “Midnight Special”. Followed by “The Confirmation” alongside Clive Owen, and two seasons on the Showtime series “Masters of Sex”. In his first film of 2017, Jaeden and Jacob Tremblay played siblings in the drama The Book of Henry (2017),with Naomi Watts playing their mother; the film was directed by Colin Trevorrow. Jaeden then starred as the lead, Bill Denbrough, in the wildly successful feature film version of Stephen King’s It (2017). He was previously credited as Jaeden Lieberher.
