US media company Turner is to make a game show version of its popular children’s show Ben 10, called Ben 10: Ultimate Challenge.

Commissioned by Turner Broadcasting, the series will be made by UK production company Twenty Twenty, which will make episodes across 12 territories including the UK, Spain, France, Italy, Holland, the Nordic region, Hungary, Poland, Germany, Russia, the Middle East and Turkey

Ben 10: Ultimate Challenge will be broadcast on the children’s channel Cartoon Network, and is the first show in the Ben 10 franchise to be outsourced to an independent producer.

Michael Carrington, chief content officer at Turner Broadcasting, said: "We’re thrilled that Ben 10 has reached a point where it merits its own spin-off show based on the popular and much-loved series. The show will be a fantastic way for Ben 10 fans across EMEA to pit their knowledge about their favourite hero against each other."

Ben 10 is one of the most lucrative boys' properties around, with Turner reporting unit sales of over 500 million in EMEA alone.

Twenty Twenty chief Tim Carter said: "Ben 10 is such a massive, creative and well-loved show for Cartoon Network, and we hope that this new format will be successful in attracting vast audiences across the territories.

"We’ve gradually built our children’s business over the past six years and this new show feels like a quantum leap forward in ambition and scale."
