Due to the simple fact that it's easier and cheaper to rely on actors from the area in which the studio's based, voice acting is usually done in separate regions. This is not always the case. If a work uses two studios based in different areas, then they have access to actors from both regions. To say nothing about home studios for personal use. Please note, this is not about an actor from one region doing work in another, this is about two regions being used in the same work.
Companies with multiple studios.
- NYAV Post, owning both New York and Los Angeles studios, practically specialize in these.
- Etcetera Group owns on office building in Miami. As such, they've arranged at least two actors (Luis Carreño and Maria Jose Estevez) to record from there, allowing them to keep their roles after emigrating.
- The Kitchen, using both Miami and Venezuela studios for dubbing, has done this a few times.
- Okratron 5000, a Texas based studio owned by Christopher Sabat, opened a Los Angeles branch (Okratron West) in 2017, during production of the Dragon Ball Super dub, to allow some Los Angeles based Dragon Ball alumni (Sean Schemmel, Kyle Hebert, etc.) to reprise their roles without actually having to fly to Texas. The aforementioned series also features Brian Drummond returning to voice Copy Vegeta.
Two companies working together.
- Steven Universe: The Latin Spanish dub, in addition to the aforementioned Maria Jose Estevez (Pearl), has done this twice:
- My Little Pony: Friendship Is Magic: Tara Strong usually records the voice for Twilight Sparkle in California after the voices for the other characters in Vancouver are recorded.
- Baby Looney Tunes: Most of the voices were provided by actors in Canada, with June Foray continuing her role as Granny in the USA.
- He-Man and the Masters of the Universe (2002) was almost entirely voiced by Vancouver-based Canadian actors, with the exception of the main character, who was voiced by California-based voice actor Cam Clarke.
- The Cramp Twins had Kath Soucie and Tom Kenny as the two titular twins, and Vancouver-based actors for the rest of the cast.
- An unusual parodic example in DuckTales (2017). Despite the cast mainly being Los Angeles-based, one episode had Andrea Libman, normally a Canada-based actress, cameo as one of a pair of My Little Pony-parodying kelpies.
- Coconut Fred's Fruit Salad Island had Canadian based voice actors with the exception of Rob Paulsen who voiced Coconut Fred.
- Many of the Marvel animated movies starting with Next Avengers: Heroes of Tomorrow saw the majority of the characters voiced by the Canadian-based The Ocean Group, with LA-based voice actors for only the main roles.
- The Last Kids on Earth has primarily American voice actors like Montse Hernandez, Mark Hamill, and Rosario Dawson, yet also uses Canadian based voice actors like Nick Wolfhard, Charlie Demers, and Brian Drummond.
- The first season of What's with Andy? played this straight, using American voice actors like Tom Kenny, Maurice LaMarche, and Colleen O'Shaughnessey, while the title character was voiced by Canadian voice actor Ian James Corlett. It was averted for seasons 2-3 when production moved to Canada.
- Similarly, Tripping the Rift features a mostly Montreal-based voice cast with the exceptions of Stephen Root, John Melendez, Maurice LaMarche, the three voice actresses for Six, and the occasional guest star during Seasons 1 and 2.
- Cyberchase is primarily recorded in Toronto, Canada, while Christopher Lloyd and Gilbert Gottfried voiced Hacker and Digit in Los Angeles.
- Totally Spies! played this straight from season 3 onwards, with production moving to Canada, and Jennifer Hale (Sam and Mandy) and Andrea Baker (Clover) still voicing their characters in Los Angeles due to dual citizenship. Season 1 also featured appearances from Ian James Corlett and Tony Daniels as guest characters.
- Inspector Gadget (2015) is recorded in Toronto, Canada, while Tara Strong records her dialogue for Penny in Los Angeles.
- Ubisoft is well-known for doing this in some of their bigger titles, such as the Assassin's Creed series featuring actors from Los Angeles, Montreal and Italy. The Far Cry games also begin doing this with Far Cry 3: Blood Dragon, which features several notable voice actors from Los Angeles while Far Cry 5 and Far Cry: New Dawn would further include voice talent from Toronto, Vancouver and Texas among its "Additional Voices" credits. For Honor takes it even further and includes Japanese voice talent like Kenji Nomura and Mitsuki Saiga as various unit voices.
- The Incredible Hulk was recorded in Los Angeles, but also featured Canada-based voice actor Michael Donovan as the voice of the Grey Hulk in the second season.
- Teenage Mutant Ninja Turtles (2003) was recorded in New York, but also featured Lenore Zann, who primarily worked with both Canada and Los Angeles recording studios, in a recurring role.
- The shows of the DC Animated Universe are recorded in Los Angeles, although Michael Donovan did voice work for some episodes in Superman: The Animated Series, while Ian James Corlett did voice work for a couple episodes of Justice League.
- The early work of Rankin/Bass Productions were mainly recorded in Toronto, including Rudolph the Red-Nosed Reindeer, which featured Billie Mae Richards as the titular character. The two sequels were recorded in Los Angeles, but still had Richards reprising her role.
