Last Week Tonight’s John Oliver and Lena Headey (Game Of Thrones) have boarded the BBC’s reboot of classic children’s animated series Danger Mouse.  The news was announced late Sunday night during a Comic-Con panel.

Oliver will voice the role of mad scientist wolf Dr. Augustus P. Crumhorn III, while Headey will be the voice of U.S. Secret Agent Jeopardy Mouse. Danger Mouse will air on kids’ channel CBBC in the fall.

“I’ve loved Danger Mouse my whole life,” said Oliver. “(It) was a significant part of my childhood. So to get a chance to do it is like getting a chance to step into your childhood, which is both a magical and a potentially hazardous thing.”

“I have children now and it’s just a treat to be involved in something that you loved as a kid and be able to share it,” added Headey, usually more noted for her R-rated escapades opposite Gerard Butler in 300 and the epic HBO fantasy series.

Brit comedian Alexander Armstrong is voicing the lead role of Danger Mouse, the eponymous British secret agent rodent. The show originally ran in the UK for over a decade from 1981-1992. The new series is a co-production between the BBC and FremantleMedia, and is being animated by Boulder Media. Ben Ward (Horrible Histories) is lead writer. Sarah Muller is exec producing for the BBC, and Bob Higgins (The Ricky Gervais Show) and Chapman Maddox (Max Steel) are exec producers for FremantleMedia, which will distribute worldwide TV and licensing rights.
