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 Carreno 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.
Two companies working together
- Steven Universe, in addition to the aforementioned Maria Jose Estevez, 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.
