Bruce Willis showed up on The Late Show with David Letterman recently and revealed that he's completed shooting A Good Day to Die Hard, and he brought a little clip along with him to share. The clip features a new title for the movie... Twi-Hard With A Vengeance, and shows us a more emotionally mature John McClane as he is thrust into despair over Robert Pattinson and Kristen Stewart's break-up. It's a fun video spoof so enjoy!
