Planet Sheen is an American CGI animated television series. It is the second spin-off of the 2001 Oscar-nominated film Jimmy Neutron: Boy Genius, as well as the 2002 series The Adventures of Jimmy Neutron: Boy Genius from John A. Davis. The show was created by Keith Alcorn and Steve Oedekerk and based on characters created by John A. Davis. The series has been picked up for 26 episodes by Nickelodeon for its first season. Jeffrey Garcia returned as the voice of Sheen, and Bob Joles and Rob Paulsen are the voices of Nesmith and Doppy. The series was originally produced by C.O.R.E. in Toronto, but production moved to Bardel Entertainment in Vancouver after C.O.R.E closed down. At that time Chris Neuhahn took over as Supervising Producer. Along with Dan Serafin, Chris Neuhahn did a substantial amount of uncredited rewriting of the last half of the season. Planet Sheen premiered on Nickelodeon on October 2, 2010 (along with T.U.F.F. Puppy) in the United States. The series was cancelled on February 15, 2013.
