Sex&Drugs&Rock&Roll cast at Comic Con: Denis Leary is a real-life doctor

He may play a rock star on FX’s Sex&Drugs&Rock&Roll, but here’s something you might not know about Denis Leary: he’s also a doctor.

“My alma mater, Emerson College in Boston, asked me to be the speaker at graduation,” Leary, who plays Johnny Rock on the new FX show, told EW at Comic-Con. “I went and spoke, and I got a Doctor of arts and letters.” (Or, as he made sure to quickly correct in the proper Boston accent, a doctah of arts and lettahs.) “It’s in my office. I’m a doctor. I mean, I can’t prescribe medicine but I’m a doctor. So I refuse to be spoken to without some respect.”

Leary and his co-stars Elizabeth Gillies, John Corbett, John Ales, Elaine Hendrix and Robert Kelly stopped by Entertainment Weekly’s Comic-Con Lounge, where in addition to waxing poetic about their fearless leader, they discussed their obsession with Leary’s hair and talked about learning how to play instruments for their roles. Leary also revealed that the casting for Gillies came from his producing partner’s three boys, who watched Gillies on her Nickelodeon show, Victorious — and joked that they now “really deserve a cut in the show.”
