When does Fillmore! return?

Cornelius Fillmore! is an American animated television series created by Scott M. Gimple for ABC and, later, Toon Disney. It originally ran for two seasons from 2002 to 2004. The series was aimed at children, but attracted an older audience with its '70s references. It maintains a dedicated fanbase and is considered a cult hit.
Seventh grader Cornelius Fillmore (voiced by Orlando Brown) is a juvenile delinquent with a record. The show is based around him and his partner Ingrid Third at X Middle School, which is located in the suburbs of Minneapolis and Saint Paul in Minnesota.
