Will there be a sonic the hedghog movie?
yes it is called sonic x
(Sonic X is not a movie, it is a TV series.)
There was one that came out back in 1999 called Sonic the Hedgehog: The Movie, and it is often referred to as "Sonic OVA."
There's actually a couple, Sonic Underground, Sonic SatAM and Sonic X and Sonic Ova, (Sonic Ova wasn't really a tv show, but it was a movie.) If you have cable, you can change it to 14, but if you can't find it, just look for KWGN and the watermark on the side should say CW4Kids on an episode. That's just for sonic x. I don't think that they show the other shows anymore.
