Born in Darlington, Co Durham in 1966, Mark Gatiss met Reece Shearsmith, Steve Pemberton and Jeremy Dyson at Bretton Hall drama school.
They formed comedy quartet The League of Gentleman in the mid 1990s and in 1997, won the Perrier Award at the Edinburgh Festival.
As a result, the League were invited to produce a series for Radio 4.
This span-off into a TV production, which brought the group great acclaim. In the meantime, Gatiss had been writing novels and appearing in semi-professional video productions based on Doctor Who.
With the success of the League's TV series, he was asked to act as script editor on the first television run of Little Britain.
Now a much sought after actor and writer, in 2007, he became one of only two people to both write and appear in Doctor Who.
He's also achieved success with his Lucifer Box series of crime books.
