Of course, no one is exactly like who I have in my head, but I think this next actor is a close match to Donavon. (Write me a comment of your suggestions if you disagree!)
Paul Wesley
If he looks familiar, that is because he plays Stefan Salvatore on the CW's The Vampire Diaries. I was hesitant to pick Paul because of his connection to a vampire story. Don't get me wrong, I LOVE good vampire stories... but I wanted to broaden my horizons a bit. The only problem was, as I would try to find other "Donavon's" to choose, I kept coming back to Paul and his spiky vampire hair. (Why do all vampires have spiky hair? You know... Edward, Stefan, Angel...).
Any good Peter suggestions?
