If they thought it would be tough to find a Biggie, then who the heck will play the Biz? From allhiphop.com:

A character driven story inspired by the true life events of DJ Marley Marl, Biz Markie, Big Daddy Kane and Roxanne Shante, The Vapors chronicles the early days of the legendary Juice Crew rap collective.

While filming was scheduled to begin in January, casting is still underway for the majority of parts in the film, casting director Red Sable told AllHipHop.com.

“We have four principals confirmed,” Sable revealed. “Clifton Powell, who will be playing Mr. Magic; Keke Palmer as Roxanne Shante; Evan Ross as MC Shan; and Cuba Gooding, Jr. as Marley Marl. All other roles are still under negotiation.”

David Banner apparently was supposed to be the Biz, but dropped out because of a “scheduling conflict.”
