I found an interesting article that discuses how "the film Groundhog Day has become a curious favorite of religious leaders of many faiths, who all see in "Groundhog Day" a reflection of their own spiritual messages."
Quote from the director "At first I would get mail saying, 'Oh, you must be a Christian, because the movie so beautifully expresses Christian belief,' " Mr. Ramis said during a conversation on his mobile phone as he was walking the streets of Los Angeles. "Then rabbis started calling from all over, saying they were preaching the film as their next sermon. And the Buddhists! Well, I knew they loved it, because my mother-in-law has lived in a Buddhist meditation center for 30 years and my wife lived there for 5 years."
