Fawlty Towers legend and Tesco ad veteran Prunella Scales and 1980s geeky Hollywood star Rick Moranis are from opposing ends of the comedy spectrum. While Moranis was goofing around on Ghostbusters, Honey I Shrunk The Kids and Spaceballs, Scales was making waves in straight roles like The Lonely Passion of Judith Hearne and Howard's End. How are the pair connected? DS will show you in five simple steps...

Prunella Scales to... Richard Briers - Before making us chuckle as Basil Fawlty's long-suffering wife Sybil, Scales found fame in the 1960s domestic sitcom Marriage Lines. Scales played lead Kate Sterling, wife of junior clerk George Sterling, played by British sitcom staple Richard Briers.

Richard Briers to... Peter Kay - Although Briers is best known for his comic turns in The Good Life, Ever Decreasing Circles and as the voice of Roobarb and Custard, he can play villainous roles as well, as he proved in Doctor Who's 1987 episode 'Paradise Towers'. Another recent Doctor Who adversary was stand-up comic Peter Kay.

Peter Kay to... Mel Brooks - Peter Kay's run of successful TV shows, which includes Phoenix Nights, That Peter Kay Thing and Max & Paddy, shows no signs of stopping. Taking a break from the small screen, Kay performed in The Producers musical, which was adapted from Mel Brooks's classic 1968 movie.

Mel Brooks to John Candy - American director, writer and comic Mel Brooks helmed the hilarious films Blazing Saddles and Young Frankenstein (and the not-so-funny Robin Hood: Men In Tights). One of his less successful outings was the 1987 Star Wars spoof Spaceballs, which featured Joan Rivers, Bill Pullman and rotund funnyman John Candy.

John Candy to Rick Moranis - Canadian comedian John Candy found fame in the 1980s with appearances on Saturday Night Live and films such as Uncle Buck and The Great Outdoors. However, he missed out on what might have been his biggest role when he pulled out of playing accountant Louis Tully in the first Ghostbusters film. The role eventually went to Rick Moranis.
