Last Man Standing (voiceover)
Petrolheads (team captain)
Motoring journalist noted for being "cute" and nicknamed 'The Hamster' (his production company is called Hamster's Wheel), partly due to his surname and partly to his somewhat small size. He also presented Top Gear, but aside from that he seems to specialise in fronting science-based shows, with credits including Sky One's Brainiac: Science Abuse and the BBC/National Geographic co-prod Engineering Connections. In 2006, he sustained serious brain injury caused by driving a 300mph jet engine car off the runway on a York airfield but made a remarkable recovery. His work on Blast Lab won him the 2009 Children's BAFTA Award for best presenter.
