I hadn't heard of people linking their beliefs to the movie. Thanks,HM;that was interesting.
I hadn't either, until I searched for it. I watched it the other day, and I couldn't help but notice the apparent symbolism relating to spirituality. I was spotting all kinds of metaphors in there. It really is a multi-theological parable, whether it meant to be or not.
Murray's character, Phil, is caught in a cycle of repeated reincarnation, until he becomes more selfless, and in doing so makes the hell in which he's trapped turn into a heaven. Furthermore, the girl, Rita, is his own personal angel, guiding him to model his outlook after her's. There are even scenes which support that symbol. After he tells her she looks like an angel when she's standing in the snow, he starts to learn how to carve angels out of ice. This can be translated in two ways: one is that he's decided to shape something righteous out of something cold, meaning himself, the other is that he's trying to learn how to carve what he believes an angel looks like, which in the end of the movie turns out to be Rita, in his final ice sculpture. In the final scene, they find themselves with a pure white town behind a gate in front of them, in which they choose to remain for the rest of their lives. It's hard to believe I didn't notice it years ago.
So, I searched for articles online about people who've made the same kinds of observations. The one I posted is the result. I like this movie more now than I did a week ago, because now the movie seems a lot deeper than before. And my favorite kinds of movies are the ones that are just entertaining if you're not looking for deep, and at the same time very deep for those who look for it.
