Career: O'Dowd made his TV and film debuts in 2003, in an episode of Red Cap and Conspiracy of Silence respectively. Other early roles came in Vera Drake, Festival, The Clinic and Showbands. Channel 4 sitcom The IT Crowd made him a star in the UK, while the movies The Boat That Rocked, Dinner for Schmucks and Bridesmaids raised his profile in the US. He then created, wrote and starred in the sitcom Moone Boy, which is loosely based on his own childhood. More recently he appeared in the films The Sapphires, This Is 40 and St Vincent.

Career: Ayoade's breakthrough came when he and Matthew Holness created fictional horror author Garth Merenghi; a stage show featuring the character won the Perrier Award, which was followed by the Channel 4 series Garth Merenghi's Darkplace. Ayoade went on to appear in The Mighty Boosh, Nathan Barley, Bunny and the Bull, and The IT Crowd. He made his big-screen directorial debut with the acclaimed Submarine (which he also wrote, adapting it from the novel by Joe Dunthorne), and has since directed The Double as well as numerous music videos for acts such as the Arctic Monkeys, Super Furry Animals, the Yeah Yeah Yeahs and Kasabian. He's was a team captain on Channel 4 panel show Was It Something I Said? and took over as host of Gadget Man from Stephen Fry.

Career: Fielding performed regularly as a stand-up comedian during the late 1990s, and appeared repeatedly on the TV stand-up showcase Lee Mack's Gas. He formed a short-lived but well-received comedy partnership with Russell Brand. His highly animated stand-up routine included surreal stories, physical comedy, characters, and songs, much like his later work alongside Julian Barratt in The Mighty Boosh, which became a monster hit when it moved to TV in 2004. He remains an active stand-up, has his own Channel 4 show (Noel Fielding's Luxury Comedy) and is a popular team captain on never Mind the Buzzcocks. He's also still a keen artist and has shown his work in a number of exhibitions.
