ET Flashback '89: Neil Patrick Harris

ET was with a very young-looking, 16-year-old Neil Patrick Harris back in 1989, when he was gearing up to play Doogie Howser, M.D. "They were looking for an unknown-ish, not a 'Kirk Cameron' face that everyone recognizes," said Neil about landing his gig after a casting effort all around the country and cattle call to find the ideal star.
