What Could Have Been: The series was initially envisioned as a live-action, TV-MA-rated sitcom (with HBO as the most likely network for it). Hearing that [adult swim] was hearing pitches for new series prompted Chris Pearson and Dan Mandel to re-work the format as an animated series. The show was brought to The Hub (a more-or-less family-friendly channel, filled with stuff primarily for children, like The Littlest Pet Shop and My Little Pony: Friendship is Magicnote other than the Brony fandom) by Margaret Loesch, former head of Marvel Productions and Fox Kids, who operated the production company which produces the show and picked up the show as the channel's founding CEO. (She jokes about launching an entire network just to give Pearson and Mandel a show.)
This show reunites actor Curtis Armstrong with animator Bill Kopp, the show's director. The two had previously worked together on Eek The Cat, which Kopp co-created and in which Armstrong provided the voice for Scooter the Caveman.
In a 2012 Comic Con panel, it was revealed that there originally was supposed to be a Dan vs. Ted episode and at least two scripts had been written, one of which eventually became the Dan vs. Dan.
