Existence Unconfirmed lost media that intrigues you the most

Trigun and Inuyasha were almost going to be on daytime Toonami but ended up going to [AS] because S&P said no. Supposedly Inuyasha was very close.


It's very likely they didn't even attempt to edit it and just heard "no" pitching the show and that was the end of it... But there is the possibility that they might have tried editing it and an edited version of at least the first episodes exist. In the unlikely event they do, I would love to see them. IDK about Trigun but the things I heard about Inuyasha implies they at least tried to edit it. 

"Special Ed", the supposed lost episode for Ed Edd n Eddy.

There was a whole boatload of fake Ed Edd n Eddy speculative stuff as I was a member of those fan boards back in the 2000s. There were hella rumors of a live action movie, or that there was going to be a theatrical release as Cartoon Network's response to the SpongeBob movie, etc. This one seemed to stick more than others.

While this episode definitely never made it passed concept stage, it does make me wonder what kind of planned stuff exists for Ed Edd n Eddy that never saw the light of day. Not lost episodes but storyboard stuff, private drawings, scripts for specials that never got approved, video games possibly, etc. 

Atlantis: Series 3
Did they finish filming and there is a full series out there?
Was it cancelled so late that they had filmed series 2 and 3 already? There was a teaser for series 3 at the end of series 2, what happened to that episode that was being teased and why has the teaser never seen the light of day since the final episode broadcasted live?
We just don't know, it was a good show it just was never going to get the numbers of Doctor Who or other mainstay BBC shows. They cancelled it very late despite clearly investing heavily after the first series but the second series didn't really gain the traction they were hoping for.
