Warwick Davis

Norton foregoes the usual physical challenges beloved of Comic Relief for a more sedentary affair: attempting to set the Guinness world record for most questions asked on a TV chat show, which should see him broadcasting into the wee hours of Friday morning. We can only hope that Graham also dispenses with his usual tipple of wine with guests, otherwise this chatathon is going to get very messy.

So far guests announced as appearing on the sofa include Ronnie Corbett, RT's Sarah Millican, Martin Freeman, Elle Macpherson, James Nesbitt, Louis Smith, Heston Blumenthal, Warwick Davis, Russell Tovey and Jimmy Carr, though you wouldn't bet against an American superstar or two turning up, too. Music acts will include Example, Paloma Faith, Hurts and Laura Mvula.

Graham will be assisted by co-hosts Terry Wogan, Frank Skinner and Nick Grimshaw, and viewers can help, too, by submitting questions via Twitter and Facebook. And by donating money.

Val Kilmer to guest star in final Life's Too Short

Hollywood actor Val Kilmer will appear in a one-off special of TV comedy Life's Too Short nearly 25 years after he and Warwick Davis last worked together.

Half an hour in the company of John Bishop would be reason enough to tune in, but he's plundered his address book and persuaded his celebrity pals to dust off their favourite one-liners.

Robbie Williams, John Prescott, Ricky Hatton, Freddie Flintoff and Warwick Davis all do their best to make us giggle, along with fellow stand-ups Jason Manford, Jason Byrne, Andi Osho and Mick Miller.

Members of the public are also given the chance to exercise their funny bone, including an impish schoolboy with a joke about poo (naturally) and a side-splitting laugh. As you'd expect from that line-up, it's a mixed bag but squeaky clean, so there's no need to cover young ears.

Warwick Davis: 'Audience matters more than critics'

Warwick Davis confirmed that he, Ricky Gervais and Stephen Merchant are currently writing a follow-up one-off special of Life's Too Short, rather than a second series.

Gervais's Life's Too Short faces an uncertain future

BBC2 mockumentary about a dwarf, starring Warwick Davis, ended run with 1.2 million viewers and divided television critics.

The sitcom that appears to prove The Office's Ricky Gervais and Stephen Merchant are creatively bankrupt, Life's Too Short distilled everything they've done before (a mockumentary format poking fun at a disabled character, with meta-jokes and celebrity cameos) but did nothing new or interesting with those ingredients. For half the seven episodes, it didn't even feel like a Warwick Davis-starring sitcom, as so much was an excuse to shoehorn in Gervais, Merchant and a guest-star-of-the-week. Things improved slightly for the last three episodes, once the storyline with Warwick's divorce became a bigger focus, but my goodwill was exhausted by then. It just wasn't insightful or clever, as everything here had been done better in Extras, and poor Warwick was forced to play himself-doing-a-David-Brent impersonation. A sore disappointment from two writers who used to demand only the best, but are now happy to devise stupid shows for their friends (see also Karl Pilkington's An Idiot Abroad).

Yes, Life's Too Short was covering old ground. Yes, it's use of celebrity cameos was lazy. Yes, it was gratuitously controversial. Yes, the physical humiliations visited on Warwick Davis became tiresome. But it was frequently very funny, beautifully performed and Davis emerged as a charismatic and engaging comedy actor. If nothing else, Life's Too Short gave an authentic starring role to a dwarf actor for the first time since... well, Willow.

Second series of Life's Too Short planned for 2013
