MUMBAI: The BBC has revealed the cast of its new high-definition children's spy series from the maker of Spooks, Kudos Film and Television.

MI High (10x30') follows a high–ranking MI9 agent, played by Danny John Jules (Red Dwarf), as he establishes a ring of undercover agents in an inner-city high school, at a time when threats to UK national security are at an all-time high, asserts an official release.

The series is the first Children's BBC (CBBC) series to be filmed in HD and follows the broadcaster's last children's show, The Magician's House, adds the release.

Newcomers Bel Powley, Moustafa Chousein-Oglou and Rachel Petladwala star as Daisy, Blane and Rose, the highly trained spies who juggle school work with saving the world. They are joined by guest stars Robert Llewellyn, Rula Lenska, Alex Ferns and Steve Furst.

CBBC head of drama Jon East said, "Filmed in HD – a first for CBBC – with jaw-dropping stunts and high-tech wizardry, MI High brings the quality of Spooks to a children's drama."

The series is due to transmit in early 2007 on CBBC, as well as being shown as part of the BBC's 12-month HD trial, available to viewers with HD services.
