My Take
For me, Seamus Dever will always be Detective Kevin Ryan from Castle, the steady, grounded half of a great partnership that anchored years of that ABC series. What I respect is the Carnegie Mellon training underneath it; that's a serious theater pedigree, and it shows in the discipline he brought to a role that could have been forgettable. Born in Flint, Michigan, he's the kind of actor who builds a long, reliable career through ensemble work rather than chasing fame. I tend to value performers like him: the ones who make everyone around them better and rarely get the credit for it.
