A charismatic, yet slightly geeky heartthrob of teen-pleasing films of the late 1980s, Patrick Dempsey succeeded in doing what few teen idols ever manage to do - disappear off the radar for several years before resurrecting their adult career as the resident hunk on one of the most popular TV shows of its time. Almost 20 years after riding that famous lawnmower to fame as the wannabe lady killer Ronald Miller in "Can't Buy Me Love" (1987), Dempsey landed the part of the stylishly coiffed neurosurgeon Dr. Derek Shepherd on the monster hit, "Grey's Anatomy" (ABC, 2005- ). Hitting a career high with this role, Dempsey became a national obsession with the female contingent, all of whom wholeheartedly agreed that the actor lived up to his infamous moniker, "Dr. McDreamy." Dempsey remained a key part of "Grey's Anatomy" until the spring of 2015, when Dr. Shepherd was suddenly killed off in a surprise twist that shocked the series' longtime fans.
