Groundhog Day is a classic comedy film from 1993.  The movie centers around Bill Murray’s character Phil Connors, who is a weatherman on-location in Punxsutawney, Pennsylvania covering the annual Groundhog Day event there.  The town’s festivities around the ritual of the groundhog coming out of his hole to check whether or not he sees his shadow are a huge media event and popular celebration which Connors, who is generally obnoxious and condescending, finds ridiculous.  On February 2, Connors has an unpleasant and miserable day in which he is annoyed by everyone around him, acts out, and totally fails to charm his producer Rita Hanson, played by Andie McDowell, with whom he is in unrequited love.  The next day he wakes up and is alarmed and confused to find that it is not a new day and February 3, but rather it is February 2 again and the prior day is repeating exactly as it happened before.

Connors winds up trapped in a time loop in which only he is lucid of it.  He experiences February 2 over and over, with his memory and knowledge retained but otherwise no evidence in the world or other people that the day has happened before and will happen again.  Connors goes through a complicated process of reckoning with this reality and ultimately makes an ambition of getting Hanson, who hates him, to fall in love with him.
