Before his retirement in 2012, the actor also worked as a stage director for productions across Los Angeles and Ventura counties.
Castillo's wife paid tribute to his career, telling THR: “Many of the actors he worked with remember him as a charismatic and insightful director who would jingle the change in his pocket while he pondered a scene, then leap onto the stage to work out the blocking or whisper in an actor’s ear.”
She added, “He was revered for providing the support and guidance that allowed actors to fully develop their characters on stage.”
