This is the remake of the 1981 Dudley Moore film of the same name.
Russell Brand plays the character Arthur who is a drunk and has so much money he can do anything he likes without any repercussions. His helper Bitterman (played by Luis Guzmán) goes along with anything that Arthur wants him to do. When the films opens Arthur and Bitterman are dressed in Batman and Robin costumes to go to a party. Arthur drives to the party in a Batmobile. They all get arrested at the party but Arthur has plenty of money to bail everyone out.
The next day Arthur's nanny Hobson (played by Helen Mirren) comes to Arthur's place to help him fix the mess he has made. Hobson is used to cleaning up after Arthur. She has been doing this since Arthur was a little boy. Now that Arthur is a grown man, his mother insists he marry. She picks out a wife for him, named Susan (played by Jennifer Garner) that he will marry because it will be good for the family business. But Arthur meets Naomi (played by Greta Gerwig) and falls in love with her instead.
Naomi is impressed by Arthur's wealth, especially when he rents out the entire Grand Central Station just so the two of them can share an intimate candle-light dinner in the massive space. But, Naomi is a more simple type of girl. She impresses Arthur by making him a dinner at her place, by heating some spaghetti from a can.
Arthur decides that to take charge of his life and to get away from his mother plus the forced marriage to Susan, he must stop drinking and get a job. This does not work out. Hobson becomes ill. She explains to Arthur how she sacrificed herself to take care of him and encourages him to go after his true love Naomi. Then Hobson dies. Arthur is so sad he starts drinking again. At the wedding with Susan, Arthur cannot go through with the ceremony. He renounces his wealth and declares his love for Naomi.
Best part of story, including ending:
This is a fun story about what it would be like to never have to grow up.
Best scene in story:
When Arthur rents out the entire Grand Central Station for Naomi, it is really impressive.
Opinion about the main character:
Arthur has the emotional maturity of a ten-year old which makes him funny but also a bit ridiculous.
