Book of Mormon type Stage

Image Credit: Ethan Miller/Getty ImagesThe long-rumored Broadway writing debut of South Park creators Trey Parker and Matt Stone finally has a date: The Book of Mormon, described as a traditional musical comedy with untraditional subject matter, will open in March 2011. Parker and Stone, who earned an Oscar nomination for the musical genius they displayed in the big-screen South Park: Bigger, Longer, & Uncut, are penning the book, music, and lyrics with Robert Lopez, a Tony winner for Avenue Q. (Lopez has said the South Park movie was one of his major influences writing the gloriously perverse puppet show.) Parker will direct with Jason Moore, who earned a Tony nomination for Avenue Q and most recently staged the irreverent Shrek the Musical. The show will be produced by Scott Rudin and Anne Garefino. The cast will be announced at a later date.

What do you think? I couldn’t be more excited. We know Parker and Stone are familiar with the subject matter — both from their 1998 film Orgazmo (about a Mormon with martial arts skills who enters the world of adult films to pay for his wedding) and the 2003 South Park episode “All About Mormons.” We also know Broadway truly has always been a dream of theirs. Music has been a part of everything they’ve ever done — from their very first film together, 1996’s Cannibal! The Musical (which is now available in its entirety on Hulu!), through 14 seasons of South Park (their 200th episode airs tonight at 10 p.m. ET on Comedy Central). What’s your favorite musical Parker and Stone moment? After the jump, just a few of mine…

“When I Was on Top of You” from Cannibal! The Musical (Parker, as Alfred Packer, who was convicted of cannibalism after leading an ill-fated trip to the Colorado Territory, laments losing his horse)

“Swiss Colony Beef Log” from the album Mr. Hankey’s Christmas Classics

Kanye West realizes he’s a gay fish

Jennifer Lopez’s “Taco-Flavored Kisses”

“Blame Canada” from South Park: Bigger, Longer, & Uncut (Okay, clearly nominated for the Oscar and shown here because “Uncle F**ka” — the hardest I’ve ever laughed in a movie theater — couldn’t be. Perhaps an idea of what The Book of Mormon will look like onstage? By the way, click here to watch Brian Boitano wish Trey and Matt congratulations on their 200th episode in a fun, profanity-laced video.)

“Montage” from Team America: World Police (I find it more pleasing to the ear than the testosterone-heavy voice Parker uses for “America, F— Yeah” and the Orgazmo song “Now You’re a Man.”)

“I’m So Ronery” from Team America: World Police (It just really shows Parker’s emotional range and his eye as a director.)
