James Anthony Patrick Carr Jr is an Irish-British comedian, known for his deadpan, satirical, often dark humour. He is a successful stand-up comedian, television presenter, author, radio presenter and actor.

Whilst working at JC Productions with his father, Carr made his first television pilot / short film at Pinewood starring Craig Charles, Roy Dotrice and himself. The mockumentary, The Colour of Funny was essentially a vanity project for Carr. He eventually gained recognition at the Royal Variety Performance, and was chosen by Channel 4 to host game shows such as Distraction and Your Face or Mine?

In 2004 he released his first stand up DVD titled simply Jimmy Carr Live, and the following year (2005) his second was released, Jimmy Carr Stand Up. A third DVD Jimmy Carr - Comedian was released late 2007 with a fourth, Jimmy Carr In Concert, scheduled for late 2008

Carr was a guest presenter for one edition of Have I Got News For You; later he joined Ian Hislop's team in the edition of the show first shown 23rd November 2007, chaired by Ann Widdecombe with whom he “flirted” outrageously. Widdecombe later vowed "I will never appear on Have I Got News for You again."

He has appeared on Never Mind The Buzzcocks twice, as well as on Stephen Fry's QI. He has presented many 100s programmes for Channel 4: 100 Worst Pop Records, 100 Worst Britons, 100 Greatest Cartoon Characters, 100 people who look most like Jimmy Carr (although this was a spoof) and 100 Scary Moments, which have made him the butt of related jokes by comedians, members of the public, and even himself.

In 2004, it was announced Carr would host a United States version of Distraction for Comedy Central. On January 10, 2006, the second season of the United States version of Distraction debuted on Comedy Central, with Carr continuing his hosting duties. Carr was shortlisted for the 2006 Rose d'Or award for best game show host. He currently hosts the quiz show 8 Out of 10 Cats.

During his guest appearance on the BBC motoring show Top Gear, Carr set a new celebrity test track lap record on the 'Star in a Reasonably Priced Car' segment. He was described as "the worst driver we've ever had" and "the luckiest man alive" by Top Gear's test driver The Stig. His re-appearance on Top Gear in May 2006 placed him last in the brand new Reasonably Priced Car, with the slowest time ever. Carr also hosted a highlights edition of the show.

Carr is also prolific writer as well as performer, with writing credits including Bo' Selecta! (C4), Meet Ricky Gervais (C4) and material for Lily Savage and Frank Skinner.

In the United States, Carr has appeared on Late Night with Conan O'Brien twice and The Tonight Show with Jay Leno three times. In December 2007, Carr presented the fourth Big Fat Quiz of the Year on Channel 4, having also presented the first, second and third. Carr has also appeared on the Irish news comedy show The Panel.
