Tonight's Culture Show, presented by Mark Kermode, comes from the Aardman studios in Bristol and celebrates the 20th anniversary of Wallace and Gromit's first outing. The lovable duo were first introduced to the British public in the short film A Grand Day Out in 1989. Later escapades, including The Wrong Trousers, A Close Shave and The Curse Of The Were Rabbit, hit gold, won Oscars and have attracted record-breaking TV audiences. A Matter Of Loaf And Death was the most watched programme on British television last year, gaining a 16½ million viewers. In tonight's programme, a mix of high-profile fans, including Sir Terry Wogan, Jonathan Ross and Ian Hislop, speak of how and why they fell in love with this one man and his dog. Creature Nick Park talks to Kermode about his creative inspirations from The Beano comic to the films of Alfred Hitchcock, revealing some surprising parallels along the way. Also in tonight's programme, actor, comedian and film star Steve Martin talks to Lauren about his love of all things banjo.
