Now, most of the trailers CAN indeed be found via this method, 
(the TRUE LIES link is actually just a small box at the bottom 
of the page). However, the one for STRANGE DAYS is a bit trickier. 
It isn't even available at the "trailers" area at all. You have 
to access the "Imaging Station" first (yes, still on the 2nd 
Abyss disc), then highlight the "Image Gallery Menus" option. 
Press DOWN on your remote. The TV monitor on that same page 
will change to show the following cryptic message -- "You know 
you want it and I can give it to you. I'm the magic man, the 
Santa Claus of the Subconscious." Then when you press 'enter, 
only then are you taken to the theatrical trailer in question 
(basically a close-up of Ralph Fiennes talking directly to the 
audience; during his monologue he repeats the lines mentioned 
above). 
Oh, one other thing -- there happens to be a SECOND trailer 
(a different one) for TRUE LIES, also on the 2nd Abyss disc. 
You have to go to "The Abyss In Depth: Mission Components." 
Once at the first page, after 'leaving' the Sub Bay, you then 
have the option of pressing 'down' to go further into the Abyss, 
OR pressing 'up' to go to the surface (this option may not be 
self-evident; the yellow arrows only show up when the correct 
button has been pushed!). Once at the 'surface', we see a nice 
seaside landscape, but at the very top of the page is a tiny 
airplane. Pressing 'up' highlights the plane, and then pressing 
'enter' takes you to the alternate TRUE LIES trailer. 
Try it yourself!
