"Bat-Mite Presents: Batman's Strangest Cases!" was pretty wild. The famous MAD Magazine "Batboy and Rubin" parody, the Lord Death Man story from the Batman manga, and a faux New Scooby-Doo Movies episode -- quite a bizarre mix. Shades of TNBA's "Legends of the Dark Knight," but much crazier.
Bold of them to open right up with "Batboy" without explaining the gag. I guess I'm not a fan of the MAD style of humor, though, since this was just okay. The "Bat-Manga" segment was very Speed Racer-esque in the animation and dubbing. I liked the gag at the end about the American dub glossing over character deaths. "I'm sure he parachuted to safety." And the Scooby segment was, well, fairly authentic, right down to the '70s-style animation/coloring mistakes.
Voice-wise, Corey Burton has achieved what's probably a unique distinction: playing both Batman and the Joker in the same episode (in the manga and Scooby segments, respectively). Plus Jeff Bennett played "Rubin" and Penguin, Frank Welker played "Batboy" and '70s Batman as well as Fred and Scooby, and Grey DeLisle was Japanese Robin as well as Daphne. But Diedrich Bader, BB&B's regular Batman, wasn't absent here; he played Lord Death Man and the "Creepy Usher" in the Scooby segment. A lot of chances for the actors to stretch. Also, Scooby-segment Robin was played by Jason Marsden, which is the second time he's played Robin -- or rather, he played Burt Ward in the biopic Back to the Batcave.
I was disappointed, though, that they couldn't coax Casey Kasem out of retirement to play Robin (and Shaggy) in the Scooby segment, and that they didn't cast a Batman actor who could do an impression of Olan Soule, Hanna-Barbera's Batman in the '70s (and Filmation's in the '60s). Welker's Batman just sounded like Welker's generic bombastic-hero voice.
