How long has Gerran Howell been acting? Well, that depends on whom you ask. Some would argue the 34-year-old Welsh actor from the coastal town of Barry had his breakout role far from home, playing a whip-smart Nebraskan farm boy and fourth-year medical student in HBO’s Emmy Award–winning series The Pitt, which features Noah Wyle and returned for a second season on Thursday. But Howell was a star in Barry long before that.

If you ask his mom’s best friend—who taught drama at his all-boys secondary school, Barry Comprehensive—she might argue that he started acting when he was 10 years old, when she cast him as a ventriloquist dummy in her production of Little Shop of Horrors, and as Puck in A Midsummer Night’s Dream. “And that’s when I got the bug,” he says.
