An expert on the history of silent cinema and a film collector, Monkhouse presented Mad Movies in 1966. He wrote, produced, financed and syndicated the show worldwide. The show featured clips from comic silent films, many from his own private collection, some of which he had helped to recover and restore. This film collection was the cause of a court case at the Old Bailey in 1979. Having lent Terry Wogan's son a film, Monkhouse was charged with attempting to defraud film distributors of royalties, but after two years the judge decided that there was no case to answer. Many of the films in his collection were seized and not returned to Monkhouse.
