Actor Patrick Dempsey has lived two charming but separate lives on film and TV. From an exuberant, somewhat awkward charmer in college comedy films of the late 1980s and early 1990s, he has morphed spectacularly into a dreamy, wavy-haired TV hunk of the new-age millennium and this seductive new image has since spilled off into romantic lead roles back on the large screen as a slightly offbeat, self-effacing Prince Charming type.
