IMDb (which relies on user submissions, and thus, not a reliable source; especially for "uncredited" entries) lists Caroll Spinney as the voice of a "Dog in Pound" in 1993's Homeward Bound: The Incredible Journey. It smelled to me of something completely fabricated, so I found it streaming (at 1hr 3min into the movie), and bust my buttons, that does sound like him:
He's not listed in the credits, either under cast or "special thanks". I tried to find a source to back it up, but I couldn't find anything online or in The Wisdom of Big Bird. Anyone know of a way we can back this up?
Yeah, we'd discussed this way back, I thought here but must have been the Toughpigs forums. The background voices, including the pound dogs, are lumped under the heading ADR Group and were recorded in Los Angeles (ADR and loop groups often include improv folks who can adlib or specialists in specific dialects, computer sounds, etc.) There's five men credited in that group, and since some of them pretty much do ADR/looping exclusively, it's hard to pin it on anyone in particular.
A lot of them do voice matching/impressions as well, so it could be just the result of trying to do a New Yorker voice or could even have been an intentional soundalike, but there's no real way to know (well, short of contacting the ADR coordinators; Mitch Carter and Newell Alexander, and the group was LA Mad Dogs which is still in business and has a website here and even then doubtful they'd recall).
For the record, here's the Homeward Bound ADR voice credits, included under the sound section (other times they will show up after the cast or stunts). The 80s and 90s is when they gradually started crediting these people (sometimes also showing up under "Additional Voices"; for Babe, the "Other Character Voices" list includes a mixture of ADR for off-screen dialogue like announcers or crowd chatter, people redubbing the New Zealand/Australian actors, and voices for background animals). Now it's fairly commonplace (even It's a Very Merry Muppet Christmas Movie credits the ADR voices, but in other instances they'll still just credit the group or coordinator, but it's less the default than it used to be except for TV series).
IMDb omits everyone in that ADR group from their entry for Homeward Bound even in the miscellaneous section where they usually park them (the British Film Institute database and other sources do include them).
Anyone think about counting the number of voiced characters who aren't listed in the credits and see if there's more than the number of credited ADR voice-overs? Which could mean that some did multiple voices, or that there are uncredited voice-overs but they don't have to be Spinney.
Yeah, that's not really helpful in this case. ADR groups do multiple scenes and voices, including indistinct crowd chatter. But the heads of the groups choose the actors, and an LA group wouldn't have flown Caroll Spinney out for a single line separate from the rest of the group. The way ADR and looping normally works, the pound dialogue would have been handled in one session (unlike animation, it's all done in post production to the film footage), then the same group people would do party dialogue (there's some of that at the beginning) or whatever was needed.
