Highlight the Lion's Gate logo on the Main Menu and press Enter to access bonus movie trailers. The reel is closed out by director Eli Roth coming on screen congratulating you on finding the easter egg.

Menu Timeouts
The disc contains a series of menu time-outs that you can find in the Scene Selections. Simply go there from the Main Menu and don't do anything. Just wait until the menu has looped a few times. Eventually the party-obsessed cop will show up and treat you to a brief clip. Try various Scene Selection pages for different clips, and if you pay attention to them you will realize that these clips actually create a small story.
