Total Riff Off Total Riff Off For the first time, National Geographic Channel has teamed up with RiffTrax, the movie and television commentary group created by the guys responsible for Mystery Science Theater 3000. So what does this mean? Your favorite Nat Geo shows with some hilariously unconventional commentary. Kevin "Servo" Murphy Next to his work for Rifftrax.com, Kevin Murphy is perhaps best known for portraying the stout red robot Tom Servo on the TV series Mystery Science Theater for nine seasons. He's also the author of the Harper Collins book A Year at the Movies: One Mans Filmgoing Odyssey. Kevin has continued to make a living out of being a culture-motivated merry-andrew, contributing to NPR's Weekend Edition Sunday and Wits. Kevin will also break into song at the slightest provocation. Bill "Crow T. Robot" Corbett Bill Corbett is writer and performer at RiffTrax, an entertainment and comedy company featuring the stars of the Emmy-nominated, Peabody Award-winning show Mystery Science Theater 3000, where Bill starred as the robot Crow 2.0. He's also an award-winning playwright and screenwriter, as well as a voice actor. His graphic novel SUPER-POWERED REVENGE CHRISTMAS comes out later this year. Mike Nelson Michael J. Nelson is the former host and writer of the Emmy-nominated, Peabody Award-winning Mystery Science Theater 3000. Since that time, he has appeared on numerous radio and TV shows, penned a regular column for TV Guide, and authored best-selling books for both Harper Collins and Abrams. Making Magic In The Studio You can be expecting a Riff-tastic journey as these guys work their commentary magic into some of National Geographic's classic series like Bad@$$ Animals, Unlikely Animal Friends, Man v. Monster, and My Dog Ate What? At the end of the three hours of Total Riff Off, you may be a little wiser and you may have even learned a thing or two, but you will definitely have a fun ride listening to RiffTrax poke a little April Fools Day fun along the way.
