Career: Jeremy was employed as a trainee journalist on the Rotherham Advertiser, but he quit while reporting on a local agricultural show because he grew tired of the marrow-growers and Pony Club mums. He joined the family firm as a salesman and moved to London, where he found a new career as a motoring writer. In 1987, he met a Top Gear producer at a car launch and was invited on to the show. He quickly became one of its most popular presenters, but left the programme in 1998 to concentrate on other projects. Other series he has fronted include Speed, Meet The Neighbours and his own chat show, Clarkson. However, he missed talking about cars and returned to a revamped Top Gear, which is now one of the world's most-watched shows.

Career: May's TV career began in 1998 with the Channel 4 series Driven, which ran for four years. In 1999, he landed a presenting role on BBC's Top Gear before it was axed due to low ratings. He rejoined the revamped version of the show in its second series. Other projects for the BBC have included Oz and James's Big Wine Adventure, James May's 20th Century, James May's Big Ideas, James May's Man Lab, and James May's Toy Stories.

Career: His broadcasting career began on local radio, before he got his big TV break hosting a number of daytime shows on Men & Motors. In 2002, he landed a slot on BBC's Top Gear, where he was given the nickname Hamster. Other series Richard has presented include Crufts, the British Parking Awards, Should I Worry About…?, The Gunpowder Plot: Exploding the Legend, Time Commanders, and Sky One's Brainac: Science Abuse. He was also a team captain on the quiz show Petrolheads and narrated the BBC series Last Man Standing. In recent years, he has started presenting serious documentaries on such subjects as warfare and engineering, and secured a world exclusive interview with his hero, Evel Knievel. He is the current face of the rather silly but very enjoyable Total Wipeout.

Career: Izzard was a street performer before tackling stand-up at the Edinburgh Fringe Festival and London's comedy clubs. He then began touring the country. Sell-out gigs led to acting roles. He's since become a star in the US and his movie credits include Velvet Goldmine, Mystery Men, Shadow of the Vampire, Ocean's Twelve and Thirteen, My Super Ex-Girlfriend and Valkyrie. He starred alongside Minnie Driver in two seasons of US drama The Riches. Izzard also played Grandpa in Mockinbird Lane, a revamp of classic series The Munsters, and has had a regular role in Hannibal. He continues to tour with his stand-up routines.
