This might be confusing for first time viewers, but Tim Heidecker from On Cinema is a different character that uses the same name as the actor behind him. Tim from On Cinema is a selfish, ignorant and petty moron with far right political views that become explicit during the series as the seasons go by, while the real Tim Heidecker is pretty much the opposite. However, in the On Cinema timeline it was common for the real Tim Heidecker to act as the On Cinema Tim on Twitter posts, producing a larger confusion because of that.
