Hi
If you`ve got a few days to spare its got to be Terminator 2 R1, with over six hours of special features, its the first DVD I have bought that I was willing to pay full price for!!!
Other than that, I recently bought Tommy Boy, hilarious comedy starring Chris Farley and David Spade!!!! A little light on extras though I`m affraid.
The New region 1 Shrek DVD looks as though it may have quite a few interesting extras, just check out the play website.
Hope this helps
