Animaniacs: Wakko's Wish -- it was released direct-to-VHS-video in 1999; right at the time Laserdisc was being phased out, and DVD was just starting to take-off .. and for some mysterious reason, it was never released in either disc format.
WW was a fitting "last hurrah" for the show, and is well-worth seeking out, even on VHS. Hopefully, with the TV series DVD's now being released, Warner Bros. will get around to this one soon.
Tiny Toon Adventures: How I Spent My Vacation -- this one
did get a Laserdisc release (back in 1992!), but has yet to see the light of DVD .. though, for that matter, neither has the TV series!
There's a lot of wonderful funny business in all 4 of the major plot threads, along with some of the cleanest & tightest animation TMS ever produced for these characters. Another 'must-see', if you can find it ..
Animalympics -- technically a TV special, though it
is feature-length. This has seen several releases on VHS; I'm not sure whether it was ever on Laserdisc (never found it, if it does exist). Animation- and story-wise, it's a bit of a 'time-capsule' curiosity now, but there should be enough of a 'cult' audience for this special to merit a DVD release, IMO ..
Pogo for President (aka: I Go Pogo) -- a nifty stop-motion adaptation of Walt Kelly's classic characters, with much of the dialogue and business coming straight out of the strip (and, like the strip, often sidelining the 'plot' for non-sequitur vaudeville shtick). This was released direct-to-video by Disney back in the dawn of VHS -- 1980! and AFAIK, hasn't been re-released since ..
The Pogo Special Birthday Special -- Chuck Jones' "take" on Walt Kelly's world, from roughly a decade earlier. Decidedly less successful in capturing the 'style' of the strip, though it does have its poignant moments. Another 'early days of VHS' release, which has yet to re-surface ..
Race for Your Life, Charlie Brown and
Bon Voyage, Charlie Brown (and Don't Come Back!) -- The third and fourth
Peanuts gang features. Hopefully, these are coming in the near-future (since Paramount did release the first two
Peanuts features on DVD earlier this year).
Race for Your Life, CB is actually somewhat 'epic' in scope, and has the most complex plot of any of the features.
Bon Voyage, CB is arguably the 'weakest' feature story-wise, but still has some great bits. As an aside, many of the
Peanuts TV specials are also MIA .. (though the major 'perennial' ones are all out there) ..
==================================
Cats Don't Dance -- yes, this one
is on DVD .. but it's only available in pan & scan 'full frame' -- a travesty, since the film was shot in 1.85:1 widescreen (and used every inch of that space). Happily, the Laserdisc release of
CDD is 'letterboxed'.
