B-Roll footage:
From the disc's Main Menu go to the 'Special Features.' Here press RIGHT to highlight the 'spaceship'. If you press ENTER now, you will get to see some B-roll footage with make-up tests!

More B-Roll footage:
On the second page of the Special Features Menu you can do the same thing and highlight the Pyramid. This will allow you to watch even more additional behind-the-scenes footage - this time a mob scene clip!

Stunt Clips:
If you highlight the hidden elements in the 'Cast & Crew' section you will get to see a stunt test clip, and in the Languages Menu you can access yet another brief stunt test clip!

Bazooka shot:
Another clip can be found in the Scene Selections Menu on the disc. Go to the 'Scenes Selections' for chapter 7 - 12 and scroll through all of the chapters until you highlight a hidden 'Psychlo image'. Press ENTER and will bring up a scene of an extra shooting a Bazooka!

Hidden Clips:
If you watch the film with the audio commentary on, occasionally a 'Psycho letter' will appear on the screen. Selecting it will then take you to some interesting behind-the-scenes footage of that particular scene. All these clips from the commentary can also be accessed directly with your remote control. Simply go directly to titles 19 - 32 and you'll get straight to these clips!
