"We talked about maybe some day doing a movie to sort of end it all, and that seems like the best idea," Parker said. "That's been a big thought to do the last show as a movie."
Parker and co-creator Matt Stone are signed on to produce episodes for Comedy Central through 2011, but it wasn't clear if they wouldn't renew that contract, or if a movie might be the last we see of Cartman, Kyle, Stan and Kenny.
Parker also talked about a South Park movie idea they previously had, which turned into the wildly-successful three-episode run, The Imaginationland Trilogy, which won an Emmy for outstanding animated program of an hour or longer.
"We came up with this pretty good idea for a movie, and then of course what happened was we got in the middle of a South Park run, and were completely out of ideas," Parker recalls. "And we were like, well, we've got to use the movie idea. And that became Imaginationland."
