Arthur

Arthur (played by Russell Brand), the heir to the wealthy Buck family, is a well-known Peter Pan-like figure in New York City. His ridiculous behaviors such as dressing up as Batman and running rampant have been reported frequently, which has made his mother who is in charge of the family company feel pressured. Arthur's behavior like an ignorant child repeatedly requires the old housekeeper Hobson (Helen Mirren) to clean up the mess. His mother cannot bear Arthur's behavior of smearing the company's reputation, so she threatens Arthur to marry his capable female assistant Susan by cutting off his financial resources. Susan has career ambitions and wants to rely on this marriage to enhance her status as a builder. Seeing that Arthur, who had bowed to his mother for the sake of money, ran into an unlicensed tour guide Naomi (Greta Gerwig) on ​​the street, the latter's charm made Arthur fall in love. At the fork in marriage and love, Arthur hopes to find a perfect ending, and this may be the strongest challenge he has ever faced.
