Two final points, one small and one large, I want to bring up involve the story and the script, which was nominated for an Academy Award for Best Original Screenplay. Let's start small first. Nolan was so detailed when writing the script that some of the character names are allusions. Ellen Page's character Ariadne is an "architect" who creates the various dreamscapes, which are designed like mazes. The name alludes to a princess in a Greek myth who aided by the hero Theseus by giving him a sword and a ball of string to help him navigate the labyrinth, which imprisoned the Minotaur. Ariadne in the movie aids the hero Cobb and the rest of the characters on how to navigate the dream mazes.
The other point I must bring up when talking about Inception is the ending. The ambiguous and controversial ending involves a spinning top wobbling. For the characters in the movie they each have a totem that allows them to find out if they are dreaming or in the real world. For Cobb if the top stays spinning he is dreaming but the ending fails to show if the top falls or not because of the abrupt cut. In other words the audience is unsure if the final sequence of the film is reality or just another dream. While many of speculated and even came up with theories involving Cobb only wears his wedding ring during dreams and that is your clue to look for, Nolan has denied this. When I first saw the movie I was a little confused and looked for clues to find out what happened but after my second viewing I realized how it doesn't matter what happened. Whether he is dreaming or not, Cobb is not looking at the top for the answer but is looking at his kids. If he doesn't care, neither should we. Nolan has backed this in interviews but the audience is free to believe whatever they want. Maybe they should sleep on it and dream their own ending to this wild movie.
