Maybe it's a little "off" -- or maybe not! -- but when I created Thomas Rathburn for Dreams of the Dark, I wrote him as a character I would not only have liked to have seen but have gotten inside of if I could be an actor (I have all the acting prowess of a ventriloquist's dummy on a skateboard.) He's an outsider, looking in on the people and places of the Dark Shadows world; but as events progress, he is drawn into an ongoing drama, eventually becoming an integral part of it.
That said, I've never seen myself in Rathburn's physical shoes (mine are more like Danny DeVito's). When I was writing the character, I envisioned Gary Cole (Night Caller, American Gothic) as the perfect actor to portray him.
