Roger Corman is a producer of over 350 films and a director of 50 more, and a good handful of those movies - fifteen total that he's affiliated with - have made appearances on MST3K throughout the seasons. He, however, is not a fan of the treatment, and the few of his movies that have been released are due to their being in the public domain.
Recently, Shout! Factory (the company currently distributing boxsets) reached an agreement to release Corman's movies on DVD and Blu-ray. Keep in mind, this isn't totally out of nowhere, as Corman is responsible for some fairly reputable films. But MSTies are greatly interested in whether Shout! distributing the films will help pave the way for getting episodes with his movies released onto future boxsets.
Of course, this relationship is still in its first steps, so only time will tell. Still, there's now a bit more hope to hang onto.
