Jonny Cruz was born Jonathan Willie Hernández in El Paso, Texas on December 1, 1982 and is the son of Maritza Pagan and Orlando Hernández, younger brother of two children with his sister Sharlene. Jonny chose to use Cruz as his professional last name in honor of his Grandmother Nayda Cruz. He attended school in El Paso and studied abroad in Würzburg, Germany in early grade school. Cruz started acting and performing in his early years in the fourth grade with his first role as Brom Bones in the play Sleepy Hollow. He continued his studies and never lost the chance to keep performing at Eastwood High School and went on to study acting and filmmaking at the University of Texas at Arlington. The ability to be so completely lost in the moment and find perfection through performance and filmmaking attracted Cruz to the art form. Cruz found himself fascinated with Improv comedy performance and joined the well known Four Day Weekend Performance Team in Fort Worth. While performing, Cruz continued to shoot short videos to showcase his comedic and technical talents.

Cruz studied computer science, acting, filmmaking and communication media, all of which he used to understand the complex process of film making. His computer skills allowed him to work as web designer and his passion for acting always prompted him to audition for movie roles as they came. Cruz stated, “I loved to learn so, I would spend endless hours working on the computer learning editing software, visual FX programs, I felt that I could pretty much make a movie on my own from beginning to end after learning all the different aspects of movie making”. So in 2005, with enough knowledge on technical and theoretical aspects of movie making, Cruz made his first incursion as writer, director and producer, besides his acting role, with Cool Wheels where he co-worked with college friends Robby Storey and Kim Matula. He then went on to produce, write, act and direct Small Timers, his first feature-length film. Small Timers took six years to complete due to severe technical difficulties, and Cruz stated that completing the film was one of the hardest things he’s ever had to do.

In 2013, Cruz featured as Jimmy Romero in the film Infiltraitors, his third production with Sabbatical Pictures. His first and second works with this company were Exit Speed and Haunting at the Beacon. Infiltrators was Cruz’s first lead in a feature film. Also in 2013, Cruz performed Victor in the action film Gone Missing.

Since 2016, Cruz has appeared as the voice of Lúcio in the highly popular game Overwatch, and reprised the role for Heroes of the Storm.
