I think Anchor Bay tried to release it last year, but was shut down. In
England, the movies made from the episodes have been released (region 2,
of course). Other than that, I have no idea when (or if) they will be
released. I thought Warner would have the rights since they own the
majority of the MGM film library. Who knows? I'm also waiting for
Warners and 20th Century Fox to get their act together so Fox can
release the '60's Batman tv show.
And I've been yelling since I first commenced it, I'm against it.
