Bet you didn't know... According to his IMDb profile, Seamus is a vegetarian.
Seamus Deaver plays Detective Kevin Ryan on Castle, and he's a pretty smart cookie. The Michigan-born, Arizona-raised actor graduated as valedictorian from his high school class, completed his degree from Northern Arizona University in just three years, and then went on to receive MFAs in Acting from Carnegie-Mellon University and The Moscow Art Theatre. He's well known for his work on Army Wives and General Hospital, but has also appeared on Mad Men, Cold Case, Charmed, Close to Home, Without a Trace, Ghost Whisperer, JAG, and Navy NCIS. He's a lifetime member of The Actor's Studio, which means he totally hangs with James Lipton. Or at least that's how we'd like to imagine it.
