Child actor-turned-reality star Christopher Knight will host the game show based on Hasbro’s “Trivial Pursuit” board game.

Mr. Knight, who parlayed his role as Peter on “The Brady Bunch” into VH1 reality series “My Fair Brady,” will begin production on “Trivial Pursuit: America Plays” this week for national syndication by Debmar-Mercury.

The half-hour show, set to debut Sept. 22, will offer contestants cash prizes for correctly answering a variety of trivia questions, some of which will be submitted by viewers via a Web site.

The “Trivial Pursuit” pilot was hosted by “Temptation Island’s” Mark Wahlberg.

“This is a game that has been a hit in 17 countries and in 26 languages, so the opportunity to bring the brand to television with Chris in the driver’s seat is really a thrill,” said Debmar-Mercury Co-Presidents Mort Marcus and Ira Bernstein in a statement Tuesday. “With Chris at the helm, we are sure that this show will find a very passionate audience.”
