Right now, yes, right now, Tom Ruegger is posting, on his blog, tons of concept and development stuff from a pitch he made to Warner Bros. a few years ago tentatively titled “Mixed Nutz”.
The premise was that the Looney Tune gang would combine with the stars of various Hanna-Barbera cartoons resulting in hilarious and totally improbable situations, such as Yosemite Sam trying to date Wilma Flintstone.
Sadly, it got passed up, but not before Tom did some preliminary show development. He’s currently posting tons of story ideas over on his blog. The posts would be well worth checking out anyway, but even more so in light of the Looney Tunes reboot that Warners went ahead with.
