Wanna know the actor involved in "Darkwing" who has had the longest-running career? Easy answer; that'd definitely be Michael Bell, whose IMDB filmography stretches all the way back to 1958. No joke. And he's currently still working regularly, on "Rugrats" and for voices in video games, among other things; so that makes 45 years of steady career. The man is hot.
Do I know how old he is? No. Where he's from? No. Anything about the guy at all other than most of the movies, TV shows, and cartoons he's been in? Nope. I'm kinda stuck, here. ;) I can't even say when I first became aware of him, although I know it was before "Rugrats" because when that came on I went "Hey, I know that guy!" ^_~ He was a mainstay of '80s cartoons that I watched; "Snorks", "G.I. Joe", "Spider-Man and His Amazing Friends", "He-Man", "Transformers" - all the old classics, and even a few of the really dreadful forgettable ones, tended to have Michael Bell show up in them. Leaves me wondering if there were actually two or three of him, or if he just didn't sleep. *G*
Anyway, particularly interesting about Mr. Bell's lengthy, and widely varying, career is that he always gives a quality performance. Quackerjack is proof of that; Michael Bell does not phone it in. He really throws himself into the role - something like Quacky must require a good deal of energy, what with all that laughing, and he always delivers. And then you turn around and have two separate roles on "Rugrats" during the same year - the uptight yuppie parent Drew, AND the neurotic geek parent Charles. Like I said, when does this man sleep??
Michael also has a large number of live action appearances, for those wishing to track him down. He's been popular with "Star Trek", having been in the pilot for TNG and a couple of DS9 episodes; he was on "Dallas" back in 1980 as Les Crowley, and had guest appearances in a surprising number of classic TV series - "Hunter", "Charlie's Angels", "Three's Company", "The Monkees", "Scarecrow and Mrs. King", "Remington Steele", "M*A*S*H", "Get Smart", the list goes on and on.
Michael Bell caught on film
(I got this at The Toon Obsession's page to Michael Bell, but I think they got it someplace else.)
Of course the listing of roles will have to be heavily abridged, and I'm going to keep it to just a voiceography here. But I urge everyone to check out Michael Bell's listings at IMDB - they're really amazing.
