While watching an old episode of Law and Order: SVU on USA tonight, I recognized a familiar face, who was then referred to as a familiar name; Kellerman. The actor was Paul Adelstein playing character Steven Kellerman in the episode. I recognized the face and name because Adelstein currently plays Agent Paul Kellerman in Prison Break (which I have a full-blown addiction with). This whole thing made me wonder how often a fictional character has made appearances in multiple shows/movies. That would take some digging to figure out, and I am too tired.
