The network has agreed to air seven episodes of an as-yet-untitled series that pits a neighborhood of families against each other for a significant prize. The series has just started casting, and no airdate is set.
Warner Horizon/Next Entertainment will produce the project, which will mark Fleiss' first new reality show to hit the broadcast networks since ABC's "The Great American Dream Vote" last year.
The series marks the first reality greenlighted by Jennifer Bresnan, CBS' new reality chief who in August replaced Ghen Maynard.
Fleiss is best known for ABC's longtime series "The Bachelor," which is considered a conceptual spinoff of Fleiss' headline-making Fox special "Who Wants to Marry a Multi-Millionaire?" Fleiss also produced ABC's infamous "Are You Hot?" and TBS' "The Real Gilligan's Island.
