Wow! I'm surprised I missed out on hearing about this news when it was first released. I'm definitely curious to see if this will go anywhere and will likely see the movie if the project doesn't end up getting scrapped. I remember watching all of those cartoons at least a few times growing up, and some of them, I watched more frequently than that.

i'm more interested in the new hey arnold movie, since it was in development before the show got cancelled, that and there was little reference to arnold's parents so it'll be nice to see where it goes as an origin story.

Mash-ups are always fun. Just look at Space Jam and House of Mouse.
