Swimming the Thames, appearing in Doctor Who and writing sitcoms and books: there's no stopping David Walliams at the moment.
David Walliams must be in the running for the title of 'the busiest man in showbusiness'.
Not content with writing children's books, appearing in Hollywood films, penning his own sitcom and autobiography and starring as a cowardly alien in Dr Who, he has just completed the admrable feat of swimming the River Thames and raising nearly a million pounds for charity as he wades through dirty London water and sewage.
After his marathon 140-mile swim ended in triumph today, you can next see Walliams acting as a 'cowardly' alien from the planet Tivoli in this Saturday's BBC episode of Dr Who ;.
The 40-year-old comedian was branded 'the nation's sweetheart' today by his mother Kathleen as he finished a gruelling swim of the Thames that has brought him applause, praise and a nasty bout of diarrhoea.
More importantly, the comedian's efforts have raised close to £1million for Sport Relief.
You have to take your hat off to man of such wide-ranging interests. He has written four children's books so far and is already planning another. It's a reflection of a strong family interest in children's education. His mother was a lab technician in a state secondary school in Surrey and his sister is a teacher and a tutor.
His latest book Gangsta Granny is out in October but he has also been working on a BBC drama called The Royal Bodyguard with David Jason. Walliams, who wed model Lara Stone this year, will be on the big screen in the forthcoming movie remake of Great Expectations. His book Mr Stink was made into a musical which is presently touring the UK and his autobiography is due out in 2012.
He also leaped at the chance to appear in Dr Who. In an interview with the Dr Who Magazine, he said: "I really feel I'm in a science fiction show on a huge scale. I know when I watch it on TV, I'll go 'Wow'
In the interview - between Walliams and Dr Who star Matt Smith, Walliams reeled off a list of the Doctors he had met: "Tom Baker, Peter Davison, Colin Baker, Sylvester McCoy, Chris Eccleston, David Tennant . . . and the new git."
Asked what he would bring to the role of Doctor Who if he ever became the main man, he joked: "Campness".
At the moment he has put on hold TV follow ups to his successful Little Britain and Come Fly With Me collaborations with Matt Lucas as he focuses on writing solo his own sitcom about teachers. Walliams said: “I wanted to do a show about teachers in a school. Cause I thought it’s been a while since someone really defined that. It’s a very universal experience. I mean most of us have been at school or maybe have kids at school. But I’m in the very early stages of it, but I’m very excited about it.”
