and that’s not counting the commercials!!
Though that does raise the question of whether we count those as truly different shows, vs. slight renamings of the same show.
David Boreanaz is trying to edge forward in the live action category. He’s going to star in the remake of The Rockford Files. We will have to see if it lasts
June Foray?
I wonder if he’ll be allowed to park his house trailer on the beach in the remake. That was a pretty nice arrangement.
She was, of course, an incredibly prolific voice actor, with TV credits dating back to the 1940s (and radio credits to the 1930s). Scanning through her IMDb credits, there are a lot of “additional voices” credits, and credits which were for only one or two episodes of a series (which wouldn’t qualify for the question in the OP). But, even so, there were many animated series in which she was a cast regular, voicing a specific main character, most notably Rocket J. Squirrel.
James Garner’s daughter said Boreanaz reached out to her to get her blessing before he agreed to the role. I think that’s pretty cool. I think he can do a good job in the role but the key is the other actors around him. Noah Berry, Joe Santos and Stuart Margolin will be hard to replace. I hope it’s better than the new version of Magnum PI. That was a snooze fest. They forgot that the strength of the old show was the personality of the characters. Jay Hernandez is handsome but he was very flat in the role. It’s the same with Rockford. People watched because they liked the characters not because of any mystery.
Where did his waste water empty? 
That is something that is noticeable about successful voice actors. Even if they are the lead actor in multiple works they all seem to also take a lot of small “additional voices” -like roles. I suppose the key to the job is to keep working. That’s why I’ve heard stories from several saying they would watch something and suddenly say, “I think that was me.”
Is there a such thing as a non-prolific voice actor? Seriously, there’s like a dozen voice actors who do everything. They usually get paid scale so they keep a tight rein on the jobs.
Depends on your definition of “non-prolific,” I suppose. There are far, far more than “like a dozen” (I realize you were probably exaggerating), though there are certainly some who seem to be in just about everything.
This website purports to list voice actors, ranked by how many credited roles they have. The top ones have literally several thousand credits – and, you’re right, many of these are the names that have been mentioned here, and/or are likely recognizable to anyone who regularly watches animated TV. But, the person down at #100 still has 374 voice-actor credits.
AFAICT, voice acting isn’t that different from other forms of acting: there’s a relatively small proportion of actors who work regularly/continuously, and a whole lot who spend most of their time doing their “day jobs,” and auditioning for the occasional acting role.
I was exaggerating, but you know what I mean. There is a relatively small fraternity of actors that do the lion’s share of the voices. Your Frank Welkers, Dee Bradley Bakers, Rob Paulsens, Tara Strongs, and so on. But, yeah, you made my point. VO actors are hella prolific. Acting isn’t really as lucrative as people imagine, VO especially so, as you can be replaced a lot more easily than on camera talent. They want to be hireable and not price themselves out of these jobs so they make up for it in volume and virtual monopolies with casting directors. I know one of their biggest peeves is when studios bypass them for “stars” that don’t add much other than marquee value. Chris Pratt as Mario? But hey, “various” pays the rent.
