In the opening scene we see Hank staring at a computer screen, trying to write something. However, the open screen is clearly a blank page in Adobe Reader, noticeable by the gray bar on the left with the icons. Adobe Reader is not for composing files.
When Charlie enters the hotel room the collar of his shirt is rumpled and stretched with finger marks as if it had been grabbed and they were shooting another take of the scene.
