Only Two South Park Voice Actors Appear In Every Episode
Besides focusing on the central group of four friends that make up the irreverent cartoon comedy, "South Park" is known for its massive cast of supporting characters and its quick lampooning of topical events. The turnaround time for "South Park" episodes follows an absolutely break-neck pace that sees many of them crafted in just a week's time, though this often allows the creators of "South Park" to address subjects that are still very fresh in people's minds.
Created by longtime friends Trey Parker and Matt Stone, "South Park" kicked off in 1997 and has well over 300 episodes that span presidential elections, weird celebrity cults, stomach-churning chili, jaunts into physical manifestations of imagination, and several forays into Canada (to just name a snippet of the absolute insanity that occurs on the show).
Both Stone and Parker voice the main characters of "South Park," which include Stan (Parker), Kyle (Stone), Kenny (Stone), and Cartman (Parker), but it seems as if the creative duo can claim an impressive record from the show as well.
Parker and Stone naturally have voiced characters in every episode
Checking out IMDb, one can see that Trey Parker and Matt Stone are the only voice actors to appear in every single episode of "South Park." This makes perfect sense considering that the two are responsible for creating "South Park" and they voice all of the main characters, extending far past Kyle, Kenny, Stan, and Cartman.
The two also voice several other characters in the show; Parker voices Randy Marsh, PC Principal, Mr. Garrison, Al Gore, Tolkien Black, and Lil Kim among many others. Similarly, Stone also voices an incredible array of characters which include Butters, Craig, Saddam Hussein, Jesus, and Ike. In other words, chances are that when one is watching "South Park," one is statistically guaranteed to hear Stone and Parker, or perhaps a combination of the two.
Speaking with Entertainment Weekly, Parker brought up what it is like to record "South Park," and explained, "The funny thing was, with every actor I bring into the booth on 'South Park,' I know for sure they're not going to do it big enough. You stick a mic in their face and you put headphones on, and you automatically get smaller — especially real actors who are used to being so small because the camera's zoomed right on their face picking up every little nuance. So as a director on 'South Park,' I'm always telling people to do it bigger." Statements like this can only come from somebody with a clear vision in their mind, which must be the reason why the two voice so many of their characters — that and it's probably exceptionally fun to voice a show with a best friend who also wants to "go bigger."
