Cashmore's career started out, like many of his contemporaries (including Nick Hancock and David Baddiel) at Cambridge Footlights. From there he appeared in several landmark comedies of the 1990s, as well as straight roles in The Bill, All Creatures Great and Small (as cricketer Fred Trueman, pictured below) Casualty, and Kavanagh QC.
Cashmore also worked in children's TV, writing and performing sketches on the Saturday morning show Gimme 5 and appearing in the 8th series of the cult children's quiz series Knightmare in 1994, where he played several roles; the menacing Snapper Jack the fool taker (pictured below), Honesty Bartram the potion dealer and Bhal-Shebah the Red Dragon, which he provided the voice for.
He was also a travel writer with columns in The Spectator and The Sunday Telegraph and a noted playwright, having penned the award winning Daughter, the much staged Trip of a Lifetime, and An Everyday Actor. His play Him, Her and Them was due to transfer to London's Finbrough theatre at the time of Cashmore's death which came about following an aortic dissection earlier this month.
Here is one of Cashmore's most famous appearances on Fist of Fun, appearing as The Man in the 'The Tortoise and The Man' sketch from series 1
