    Groundhog Day Screenwriter Is Tweeting And Joining Tonight's Parties!

    Danny Rubin, the guy who wrote the story and script, has just released a Kindle book on how he did it -- called "How To Write Groundhog Day." And he's online tonight to join in everyone's festivities, answer the questions you've always had (like how long did the time loop REALLY last?), and just be social with movie fans. (@groundhog_guy)
