Bill Murray's Groundhog Day is like Bioware RPGs. When the plot is over, all you can do is go back to the start. If you die, you get sent back to a different part to try again.
Video games face a lot of interesting problems whenever they want to tell a coherent story. You need an enemy that does not create any moral dilemmas if you slaughter them wholesale. The main character has to be dramatically important to the point of ludicrous. They also need to have a blank enough personality that the average person can project onto them. Even the touchstones of game narrative have convoluted plot holes. Bioshock stops making sense after the third act depending on your choices. Uncharted 2 might be remarkable for having good writing and acting but there is still a drastic difference between Nathan Drake the character and Nathan Drake the person slaughtering hundreds of soldiers. Even these games ignore fundamental elements of gameplay like loading your saved game, artificial interactions, or the natural emotional distance that all players have from the consequences of their conduct. It’s funny then that there is already a movie which has tackled most of these issues by presenting a protagonist who is stuck in a time loop.
Groundhog Day is a remarkably pliant work of art. Bill Murray (Phil Connors) is stuck repeating February 2nd in a small town in Pennsylvania. There’s no explanation for it, he just wakes up over and over to the same events constantly. An article over at suite101.com points out numerous religious interpretations of the film (Kerri Carpenter, ”Groundhog Day: A Classic Comedy With A Moral Legacy”, suite101.com, 27 Jan 2010). Catholics see it as a parable for Purgatory, Buddhists identify with the themes of self-reflection that Murray’s character experiences because he can never change the world due to the time loop. Life always resets, and no one has any memory of the things Murray did except him. Mario Sesti points out that the film’s character arc is seeing Murray’s changing relationship with this situation (”Groundhog Day The Movie: Buddhism and Me”, P.S. A Column on Things, 20 Jun 2008). Murray is stuck in the time loop long enough to learn fluent French, the piano, memorize every person in town, every event experienced in the day, and every reaction to his conduct. Sesti comments, “[Murray] becomes increasingly less the hostage of his small-town world and more its creator.”
