I was just watching Castle and realized that Richard Castle was quite the hottie, so I did a little Google search and here we go! Nathan Filion has actually acted in many roles – I’ve only ever seen him in Castle, so was quite surprise when I found out that he also in Saving Private Ryan, Buffy the Vampire Slayer (I was such a fan as a teenager), Desperate Housewives and even Lost. Yet I think his most charming (and memorable) role is as the mystery writer Castle, don’t you agree?
