Jan Luis Castellanos stars as Diego Torres on "13 Reasons Why," the charismatic and aggressive Liberty High student who is introduced in the fourth season. Closely connected to the football team and to the aftermath of Monty’s death, Diego becomes one of the season’s most confrontational new figures. His presence adds pressure, suspicion, and volatility to the story as he pushes for answers and becomes deeply involved in the conflicts surrounding the students at Liberty.
Before joining "13 Reasons Why," Castellanos begins building a career in acting and modeling, gaining attention as a younger performer on the rise. His casting in the series gives him a prominent role in a major Netflix drama and helps introduce him to an international audience. Because Diego arrives during the show’s final season, Castellanos is tasked with making an immediate impression in an already established ensemble.
In addition to his work on "13 Reasons Why," Castellanos appears in other screen projects, including "Don’t Look Deeper." These roles help broaden his profile beyond teen drama and position him within a newer generation of television actors. His work reflects an expanding career that reaches across streaming projects and youth-oriented series.
Outside of "13 Reasons Why," Castellanos continues developing his work in television and film. His role as Diego gives him a significant credit in a high-profile final season, and the character’s forceful presence makes him one of the more memorable additions to the series’ later ensemble. On "13 Reasons Why," he brings confidence, energy, and tension to a character whose loyalties and motives shape much of the season’s conflict.
