Big Bad Mouse is a frequently revived 1960s British stage play and theatrical comedic farce that, although not specifically written for them, became famous as a loose vehicle for the many talents of the British comedy actors Jimmy Edwards and Eric Sykes and has constantly seen various revivals with other stars right up to 2008.Written jointly by Phillip King and Falkland Cary, from an original idea by Ivan Butler, Big Bad Mouse was first staged in 1964 but did not become a box office hit until Edwards and Sykes took over the lead roles and toured the show across the UK in 1966 and 1967.
