Nickelodeon is developing a Nicktoons movie which is essentially Who Framed Roger Rabbit meet Space Jam meet The Lego Movie. It will featured a lot of iconic Nicktoons characters (Except Ren & Stimpy due of tensions between the show's creator and Nickelodeon)
So I wonder what if Cartoon Network made their own film about iconic Cartoon Network Characters?
I think their film will be different than Nicktoons films. This video will show of what would their film look like.

Between 2004-2007, Cartoon Network created CN City which is a Third era for CN and they used this bumper to show off their characters living in that city. It was eventually defunct when Stuart Snyder become their new president. I wish they bring back this concept for new audience.

I think their film will be similar to CN City Bumpers. Just saying
