I made up an idea for an Ultimate Muppets Box Set a while back there. I've been tinkering with it since that. Now, assuming MT would fit on 2 double-layer discs, it would fit on 1 double-sided-double-layered disc. Here's a revised edition of that set:
The Muppet Treasure Chest: HIT edition
Disc 1: The Animal Show A 13-ep "best of" on 1 2-sided 2-layered disc. Extras: Commentaries on most eps with Brian Henson, Dave Goelz, Karen Prell and Steve Whitmire; a Frank Oz commentary on the "Bald Eagle" episode in which he guest-starred as Sam; a short documentary on the show.
Disc 2: The Ghost of Faffner Hall Entire series (13 eps, I think) on 1 2-sided 2-layered disc. Extras: Commentaries on all eps by Louise Gold, Karen Prell and Mike Quinn; a short doc on the series; a profile of the Wild Impresario.
Disc 3: The Secret Life of Toys 13 eps (possibly the entire series?) on same disc as the other 2. Extras: Commentaries by Louise Gold, Jerry Nelson and Dave Goelz on all eps; short doc on the show.
Disc 4: The Specials "The Christmas Toy", "Tale of the Bunny Picnic", "Hey Cinderella!", "The Frog Prince" on same disc as before. Extras: Commentary on "Toy" by Goelz, Whitmire, Henson and Kathy Mullen; "Picnic" by Whitmire, Clash and Prell; "Prince" by Jerry Juhl; short docs on each
Disney doesn't have a whole lot to release, so I'll leave that for another day.
