Genndy Tartakovsky was approached to adapt Orion, "around 2015"

In an Instagram post six weeks ago, Genndy Tartakovsky says he was in the running to helm the Orion and the Dark film adaptation. Tartakovsky is the creator of Dexter's Laboratory, Samurai Jack, and Star Wars: Clone Wars, among others.

Since Netflix released a trailer I thought I would share. I don’t think I’ll get in trouble for this…so here goes.
Around 2015 I was asked to develop a movie based on this children’s book called Orion and the Dark. So I came up with a version where the kid has to travel to the Dark World to get rid of his fears of the dark. In that world everything that he fears in the real world is explained and actually nice. I was pretty excited about it but then it went the normal path of Studio development...fear, confusion, doubt, etc. So I moved on and now they made it. So here are my original sketches. (Source)
