These days, Neil Patrick Harris is practically a household name. But that hasn't always been the case. Before he was one of the biggest stars in Hollywood, besties with Elton John, and an equal rights icon, Neil was just a 16-year-old child star cutting his teeth on "Doogie Howser, M.D." In honor of the 20th anniversary of the "Doogie" finale on March 24, 1993, we're rounding up Hollywood's best comeback cases.
When "Doogie" went off the air in 1993, Neil quietly slipped out of the spotlight. He spent the next decade appearing on Broadway and in nearly a dozen made-for-TV movies. But it wasn't until 2004 that Neil made his return with the role he was born to play: a cameo in "Harold & Kumar Go to White Castle." His portrayal of himself as a stripper-loving, drug-abusing bad boy helped Neil shed his wholesome boy-next-door image, announced him as a comedic force, and opened the door for Neil to play womanizer Barney Stinson on "How I Met Your Mother." In 2006, Neil confirmed that he's gay, and now he and longtime partner David Burtka are the proud parents of fraternal twins. Not bad for a reformed child star!
