Ryan McCartan has built a unique career by bridging the gap between mainstream television, cult film classics, and high-profile Broadway musical theater. Born in Excelsior, Minnesota, he developed an early affinity for performance that quickly escalated from regional high school productions to national television screens and major theater stages. If you want to understand how he transitioned from a Disney Channel regular to a leading man on Broadway, examining his specific body of work reveals a performer defined by vocal discipline, character versatility, and a relentless work ethic.
Unlike many child stars who struggle to find footing in adult projects, McCartan navigated the shift by choosing roles that require intense physical and vocal commitment. Whether he's playing a wholesome small-town boyfriend, a murderous teenager, or a classic literary romantic lead, his career offers a case study in modern multi-platform performance.
Early Breakthroughs and Television Origins
McCartan's professional momentum began in regional theater, where he won Best Performance by an Actor at the National High School Musical Theatre Awards (the Jimmy Awards) in 2010. This early recognition opened doors for television guest spots on popular network series like The Middle, Royal Pains, and Last Man Standing.
His major television break came in 2013 when he joined the cast of the Disney Channel sitcom Liv and Maddie as Digbert "Diggie" Smalls. Appearing across multiple seasons, he became a familiar face to millions of young viewers. Instead of staying boxed into children's television, however, he leveraged that visibility to pivot toward edgier, darker material on stage and screen. Deadline has provided coverage on this critical issue in extensive detail.
Stepping Into Cult Status: Heathers and Rocky Horror
The defining turning point of McCartan's early career was his creation of the role of Jason "J.D." Dean in the original stage adaptation of Heathers: The Musical. Originating the character in Los Angeles in 2013 and taking him off-Broadway in 2014, McCartan captured the dark, charismatic menace of a high-school sociopath with chilling vocal control. The cult following of Heathers cemented his reputation as a formidable musical theater actor with a distinct edge.
That dark musical energy translated directly to film in 2016, when he was cast as Brad Majors in Fox's television remake The Rocky Horror Picture Show: Let's Do the Time Warp Again, directed by Kenny Ortega. Playing the quintessential straight-laced hero alongside a diverse ensemble cast allowed McCartan to showcase his comedic timing and physical comedy within a campy, high-energy environment.
Conquering Broadway and Major Stage Roles
While screen projects brought widespread recognition, the stage remained McCartan's professional anchor. His résumé features a string of high-profile replacements and original casting stints in some of the most competitive shows in New York City.
- Wicked: He made his Broadway debut as Fiyero Tigelaar in September 2018, bringing a grounded charm and athletic presence to the Gershwin Theatre.
- Frozen: He stepped into the role of Prince Hans, first during the final Broadway run at the St. James Theatre and later anchoring the U.S. National Tour.
- The Great Gatsby: He took over the iconic title role of Jay Gatsby at the Broadway Theatre, demonstrating his maturity as a leading man capable of carrying a massive commercial spectacle.
These roles aren't handed out lightly. They require a triple-threat skill set: pristine vocal health capable of eight shows a week, strong dramatic acting chops, and the physical stamina to sustain complex choreography.
Music and Independent Projects
Beyond acting, McCartan pursued a parallel career in music. In 2015, he formed the pop duo The Girl and the Dreamcatcher with his then-partner Dove Cameron, releasing several music videos and an EP before the group disbanded in 2016.
He subsequently launched a solo music career, releasing independent EPs like The Opposite. His musical style leans into pop-rock and contemporary singer-songwriter confessionals, giving him an outlet to process personal experiences and showcase his upper vocal register outside of character work.
