Meet Ryan McCartan! The Heathers Star on His Transformation From Disney Dream Date to Serial Killer

Age: 20

Hometown: Excelsior, MN

Current Role: An off-Broadway debut as bad boy J.D. (a role made famous by Christian Slater in the 1988 movie), who convinces his girlfriend Veronica to knock off the popular kids in Heathers.

Stage & Screen Cred: Winner of the 2011 National High School Musical Theater “Jimmy” Awards; appears on the Disney Channel hit Liv & Maddie with his real-life girlfriend, Dove Cameron.

“After a sh*tty day in high school, I will openly admit that I came home and said, 'God, I wanna kill so-and-so.' Obviously I've never actually killed anyone, but I had my fair share of Heathers."

“I was diagnosed with juvenile diabetes at age six. Before, I played every sport from golf to basketball to tennis, but my body just couldn’t handle it—by the time I was eight, I had quit everything.”

“My girlfriend Dove [Cameron] and I have become one of these Disney couples that so many young girls have a stake in. I can’t tweet about a date I’m taking her on without having a bagillion 8-to-13-year-old opinions about what we're doing.”

“I shot Liv & Maddie by day and rehearsed Heathers at night—Dove thought she’d be uncomfortable watching me simulate sex with another person on stage, but when she saw the musical, she got lost in it. Luckily it doesn’t bother her.”

“When Christian Slater came to the show, I literally fell to my knees. He gave me a hug and we decided, for old time’s sake, he should try on my trenchcoat. It was absolutely surreal.”

“Most of my fans are preteens. They show up to Heathers and don’t even blink twice [at the adult content]. But hey, when I was 12, I was in the car with my sister, belting the Rent soundtrack!”
