Re: Betty Boop
The Betty Boop cartoons, along with the Fleischer Color Classics, surviving Kokos, Stone Age, Gabby, Gulliver's Travels, Hoppity Goes to Town, and all other Fleischer material except for Popeye are owned by Republic, part of Paramount. The Republic library was licensed to Lionsgate (a second time, after it initially expired).
I'm fairly sure the UCLA Film and Television Archive restored all of the cartoons years ago. So, they're ready to be remastered in HD and released on DVD. Lionsgate did nothing with them from 1997-2005 (when the contract ended), so I'm not hopeful now. They deserve the same attention WB is giving to their theatrical cartoons.
This would be a neat project for Criterion to try since they've never released animation on DVD before. They'd at least be able to meet Warner's standards.
I never thought we'd see Popeye cartoons on DVD before Betty Boop...
