I'm very ambivalent about the Back to the Future cartoon series. The new voices for Marty & Doc weren't entirely convincing.
Marty was played by David Kaufman, who later played Jimmy Olsen in
Superman: The Animated Series and the title character of
Danny Phantom. He was recognizably not Michael J. Fox, but he had a very similar quality to his voice, so I could buy it.
Doc was doubled by Dan Castellaneta, aka Homer Simpson. It was a pretty decent impression, although I was disappointed that Christopher Lloyd, who participated in the live-action host segments, didn't do the voice work as well.
Still, though, in animated adaptations it's far more common to use replacement actors. Heck, Ernie Hudson auditioned for Winston in
The Real Ghostbusters and was turned down! So rather than being disappointed when an animated show uses doubles, I'm impressed when it uses some of the original actors. The BTTF cartoon had Thomas F. Wilson (who's done a lot of animation since then, notably
Gargoyles) and Mary Steenburgen, and that was awfully cool.
Too many of the episodes focused too much on Jules & Vern. And sometimes they would do stupid stuff to tie into the weekly science lessons, like use a bunch of lemon batteries to power the Delorean.
Well, it was a kids' show, so naturally it focused on the kids -- though I did find Vern rather annoying. And I can't fault the show for being educational -- and for being a stepping stone for Bill Nye's career as a science popularizer.
I thought the first season of the show was pretty good, but it lost its way and got more dumbed down in the second season -- the usual fate of Saturday morning network animated shows, alas.
I don't really see that. The Tim Burton movies certainly fueled an interested in the property and opened the door for darker interpretations. But it didn't seem to me like Catwoman or the Penguin looked very much like their Batman Returns counterparts.
Penguin very much did; he was given the same fat, distorted appearance and flipperlike hands, completely unlike the standard version of the character, who's just a short, long-nosed but otherwise fairly ordinary-looking guy in fancy dress. And Catwoman was required to be blonde like Michelle Pfeiffer; Catwoman has very rarely been portrayed as blonde in the comics. Note that when the producers revived the series a few years later, after the Burton films had run their course, they redesigned both Penguin and Catwoman to look more like their comics versions.
Have they done a Thor TV series? They totally need to do a Thor TV series. They've even got a ready made ensemble with Lady Sif & the Warriors Three. And make it a prequel to the movies so that Loki is still technically a good guy. I'd call the series: Thor & the Warriors of Asgard.
The 1966
Marvel Super Heroes series, which did crudely animated adaptations of comic stories, included Thor as one of its segments. They rotated between five different heroes on five days of the week, and they fittingly aired Thor's episodes on Thursdays.
But that's the only solo series he's ever had. There was apparently one announced in 2008, but it was never made. And of course the 1988 TV movie
The Incredible Hulk Returns, with Eric Allan Kramer as Thor, was a backdoor pilot for a live-action Thor series that never got picked up. Other than that, he's been a regular on the past two
Avengers cartoons and
Super Hero Squad, and has made guest appearances on various other heroes' shows in the '80s and '90s. (In his '90s
Fantastic Four and
Incredible Hulk guest appearances, he was played by John Rhys-Davies!)
He has been featured in two direct-to-DVD animated movies, though,
Hulk vs. Thor and
Thor: Tales of Asgard.
