I haven't seen any of these movies on your list either except:

The Wizard of Ox (childhood entrapment)
about half of The Exorcist.
The Omen
Oh, I have seen a couple Woody Allen movies

********

Movies I've not seen that everyone else has (beyond your list):

Braveheart
Shreck I or II
Finding Nemo
A River Runs Through It
The last two Star Wars movies
Mel's Passion thing
Brokeback Mountain
The Piano
The Silence of the Lambs
Anything with Adam Sandler in it (at least knowingly)

I'm sure there are plenty more as I watch about 7 movies a year, and that includes rentals.
