Pointless host Alexander Armstrong has landed the starring role for the return of much-loved cartoon character Danger Mouse.

The comedy actor – also known for his comic TV shows with Ben Miller – will be voicing the debonair but diminutive secret agent for his comeback next year, more than two decades after the series ended.

White-clad hero DM, who wore a patch over one eye, was previously voiced by Sir David Jason in the original shows which ran for more than 10 years.

The new CBBC series will also feature the voice of Come Dine With Me, Dave Lamb, who has landed the all-important role of narrator.

Danger Mouse ended in 1992 and his return created a buzz when it was announced in June. The character will be given a revamp and will have cutting edge gadgets at his disposal including his multi-purpose ‘i-patch’, although he will continue to have his HQ in a post box.

Alexander, 44, has previously voiced an alien super-computer in Doctor Who spin-off The Sarah Jane Adventures, as well as top engineer Professor M in the animated series Tooned.

The star – who, like his new character, went to Cambridge – said: “As a lifelong fan of Danger Mouse I was ecstatic just to know that the show was coming back. To be actually involved with the reboot and to be taking DM out to a whole new generation is about as close to a dream job as you could wish for.”

His hamster sidekick Penfold – noted for his catchphrase ‘Crumbs, DM’ – will be played by comedian Kevin Eldon, a role played by the late Terry Scott in the original shows.

He joked: “When I am recording the episodes, I’ll be making sure that at all times my eyebrows are at least three inches above my head.”

Dave Lamb, familiar to CBBC viewers as co-host of Horrible Histories: Gory Games, said of his appointment: “Danger Mouse’s narrator is an iconic role and I can’t wait to get started.”

The original show – whose title music which featured the lines: “He’s the greatest, he’s fantastic, wherever there is danger he’ll be there” – was originally screened by ITV.

Danger Mouse’s 52-episode revival is being made by Boulder Media and FremantleMedia Kids and Family Entertainment, after the company which created it, Cosgrove Hall, was closed down in 2009 after becoming part of ITV.
