Neil Patrick Harris (born June 15, 1973) is an American film and stage actor, singer and comedian best known for his roles on sitcoms like Doogie Howser, M.D. and How I Met Your Mother as well as the online musical series Dr. Horrible's Sing-Along Blog (co-starring Felicia Day).
Work on MST3k
Harris is one of the various interviewees featured in the 1992 Comedy Central special This Is MST3K, which was hosted by Penn Jillette. In 2007, Harris was one of the first celebrity guests to co-riff with Michael J. Nelson's newly founded RiffTrax on the movie Willy Wonka & the Chocolate Factory. In 2013, Harris helped promote on the various social networks the RiffTrax Live nationwide presentation of 1997 film Starship Troopers, which featured him in a prominent role. During the show, Harris had only four riffs aimed at him, all of which were rather complimentary.
In 2015, Joel Hodgson announced during the Bring Back MYSTERY SCIENCE THEATER 3000 Kickstarter campaign that Harris was one of several celebrities to confirm a willingness to make cameo appearances on the revived show. He subsequently appeared in Experiment #1104 Avalanche as magician Neville Laroy.
