Arthur- The 2011 remake of the 1981 movie about a billionaire who never learns to grow up until he has to. The title role is played by Russell Brand, with Helen Mirren, Jennifer Garner, Greta Gerwig, and Geraldine James.
Basically, Arthur is a playboy drunk who is heir to an enormously wealthy corporation, but he's threatened by his mother to be cut off unless he marries Susan, the heiress to another wealthy corporation who his mother believes will be able to control him. He's fine with going into an unhappy marriage at first, because he would rather have the money, but then he meets Naomi, and for the first time in his life, things are happening that make him realize how much he needs to stop drinking, grow up, and become part of the real world.
The movie has its moments when it is incredibly funny, but a lot of the premise and certain situations are incredibly unlikely. I've never seen the original, so I don't know if they just had bad writing to work with or if the movie didn't translate well to a modern context, but it wasn't quite on all the way through.
I saw this movie because I love Russell Brand and find him hysterical, but I don't think I would have enjoyed the movie otherwise. He pretty much played himself, which worked fine for the role, but aspects of that made other things weird. Jennifer Garner's character, Susan was very intense, which she played well, and she was also very sort of refined and collected, but that breaks down at an odd place at the end. Helen Mirren plays the nanny, and although she's fantastic, she just doesn't seem like the sort of person who would have allowed Brand's character to grow up the way he did. It was just little things like that that bugged me through this movie.
To be honest, it was more heart-wrenching than funny altogether. If you're looking for a kind of sweet and quirky movie, or if you love Russell Brand then you should like this movie. Otherwise you should look for something else.
