A double act is a form of comedy originating in the British music hall tradition, and American vaudeville, in which two comedians perform together as a single act, often highlighting differences in their characters' personalities. Pairings are typically long-term, in some cases for the artists' entire careers. Double acts perform on the stage, television and film.

Dudley Stuart John Moore CBE was an English actor, comedian, musician and composer. Moore first came to prominence in the UK as a leading figure in the British satire boom of the 1960s. He was one of the four writer-performers in the comedy revue Beyond the Fringe from 1960 that created a boom in satiric comedy. With a member of that team, Peter Cook, Moore collaborated on the BBC television series Not Only... But Also. As a popular double act, Moore's buffoonery contrasted with Cook's deadpan monologues. They jointly received the 1966 British Academy Television Award for Best Entertainment Performance and worked together on other projects until the mid-1970s, by which time Moore had settled in Los Angeles to concentrate on his film acting.
