The immature heir to a billion-dollar empire finds himself cut off from the family fortune after rejecting his arranged marriage to a nouveau riche socialite, and instead falling for a free-spirited unlicensed tour guide in this remake of the sentimental 1981 comedy starring Dudley Moore. Arthur (Russell Brand) was raised in the lap of luxury. His family is wealthy beyond compare, and ever since he was a child his every whim has been catered to by his nanny, Hobson (Helen Mirren), and his chauffeur, Bitterman (Luis Guzman). But the party starts to wind down when Arthur's domineering mother (Geraldine James) insists that he marry Susan (Jennifer Garner), the daughter of a self-made millionaire (Nick Nolte) who isn't above intimidating his future son-in-law into marriage. Vehemently opposed to the idea due to the fact that he and Susan have nothing in common, Arthur rejects the proposal after falling in love with Linda (Greta Gerwig), an aspiring children's book author who pays the rent by giving unofficial tours of Grand Central Station. As a result, Arthur has to decide if he can face life as a normal member of the working class -- and without his trusty flask of booze. Television veteran Jason Winer (Modern Family) directs from a script by Peter Baynham (Brüno, Borat).
