His Radio 1 series, Alan's Big One FM, led to TV appearances on shows such as One Foot in the Grave, before he was cast as the lead in Jonathan Creek, the light-hearted mystery drama that made him a household name. Other acting work includes Bob and Rose, A Many Splintered Thing, The Brief, Marple, Angus, Thongs and Perfect Snogging (2008), Lewis and Whites.

Career: Hall has lived in the UK for more than 20 years, though he briefly relocated to Montana, where he still owns a small ranch. In 2000, he won the Perrier Comedy Award for his performance as Otis Lee Crenshaw, a persona that has so far spawned a book and the script for a film. Hall has become a stalwart of the stand-up circuit as well as a panel-show regular, notching up several appearances on QI and 8 Out of 10 Cats. In 2003, he presented a series about fishing, before returning to the Edinburgh Fringe in 2007 with his play Best Western. He picked up the theme again a year later in the documentary Rich Hall's How the West Was Lost, one of several programmes he's made about film genres. Hall has also published several books, and is an accomplished musician.

Two years later he appeared opposite Mel Gibson and Anthony Hopkins in The Bounty. In the late 1980s he played Lionel Zipser in Porterhouse Blue, appeared regularly on Whose Line is it Anyway? and starred in his own one-man TV show, simply titled John Sessions. He has also appeared in Henry V and In the Bleak Midwinter, both directed by old friend Branagh.
