Arthur is a 1981 American romantic comedy film written and directed by Steve Gordon. It stars Dudley Moore as Arthur Bach, a drunken New York City millionaire who is on the brink of an arranged marriage to a wealthy heiress but ends up falling for a common working-class young woman from Queens. It was the sole film directed by Gordon, who died in 1982 of a heart attack at age 44.

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.
