CBS is teaming with “Big Brother” exec producer Allison Grodner for a new quizzer in which adults will match wits with child geniuses for a shot at $1 million.

Untitled hour has an ensemble cast of several kiddie prodigies taking on one adult contestant each week. The adults will try to defeat the kids, while the kids will be charged with protecting $1 million bank.

Eye reality and CBS.com programming guru Ghen Maynard is developing the project with Grodner via Allison Grodner Prods. Casting has begun for the project, which is being put on a development fast-track.

“We’re looking for really spectacular young minds, the Doogie Howsers of the world,” Grodner told Daily Variety. “The kids will be trying to outsmart the adults, and the adults will be trying to outsmart the kids.”

Cast of small geniuses will return every episode, allowing auds a chance to get to know the kids. It’s possible some of the kids will have specialized areas of knowledge, with the adults having to take on all of the kids in order to get the coin.

Maynard said he hopes the show will be “amusing but also relatable.”

“I think little kids are people we all identify with, wherever we are in life,” he said.

Focus of the game will be on the adults trying to get the $1 million booty. “But there will be incentives and other forms of compensation for the kids,” Grodner said.

Grodner and Maynard cautioned that the show is still in the early stages of development and some details are still in flux.

CBS project is one of several network quizzers either in the works or already on the air. Eye is developing a new take on “Name That Tune,” while NBC this month will unveil its third quizshow, “Identity.”

Grodner’s repped by CAA. She’s exec produced the Eye’s “Big Brother” for the past six years with Arnold Shapiro via Endemol USA and Shapiro-Grodner Prods.
