Actor; He is famous from Doogie Howser, M.D..

Perfomed as Mark in "Rent" at the Ahmanson Theater in Los Angeles to rave reviews Based on his Los Angeles stage performance in the musical Rent, he was attached to play Mark Cohen in a television mini series based on the Broadway musical, with Wilson Cruz as Angel, Rikki Lee Travolta as Roger Davis, and singer Shakira as Mimi, but the rights were pulled in order for Chris Columbus to make a film adaptation using much of the original Broadway cast including Anthony Rapp in the role of Mark. Best friend is Amy Acker. Loves puzzles and word games. He was the "Not My Job" guest on the April 5, 2008, episode of the National Public Radio quiz show "Wait Wait... Don't Tell Me!".

Typically, actors playing themselves on film are listed "as Himself" in the film`s credits. Due to the over-the-top, outlandish nature of his role in Harold & Kumar Go to White Castle (2004) and Harold & Kumar Escape from Guantanamo Bay (2008), he requested that his credit read "Neil Patrick Harris" instead of "as Himself." This was to make clear that he was playing a fictional character that was in no way a true representation of himself.

Has performed magic tricks on "The Tonight Show Starring Johnny Carson" (1962), "Late Show with David Letterman" (1993), "The Tonight Show with Jay Leno" (1992), and "Ellen: The Ellen DeGeneres Show" (2003).
