Behind the Scenes:
Go to the "special features" menu where it has a list of the different scenes such as the handtrap and the needle pit. On the headtrap title, press the arrow right and the key icon should appear bigger and on the right hand side of the screen. This is another feature called "bits and pieces" which shows other different props they used for the film.
