So it occurred to me to wonder whatever happened to Spaceballs: TAS. It was announced about two years ago and I haven't heard anything about it since.
Well, apparently it's still happening (though the "this fall" referenced in the trailer below is actually last fall, so when is still anybody's guess).
http://www.youtube.com/watch?v=TS3MhoPBqooWikipedia says it's already debuted in Canada, but I've been unable to find any eps torrented as yet.
Apparently Mel Brooks, Daphne Zuniga, and Joan Rivers reprise their roles from the movie, while Tino Insana will be playing Barf, Rino Romano will be Lone Star, and Dee Bradley Baker will be Dark Helmet.
EDIT:
TV IV pegs the premier date as 9/21. If I had an account there, I would probably slap a "needs citation" on that. Suspiciously, 9/21 is the same date the series was first announced in 2006; best guess is somebody hit Google, saw a bunch of matches for "spaceballs animated" that had "September 21" next to them, and didn't read the fine print.
