On fandango.com it shows a blip about the preview, and says something like "Click here for more information." Click there, and you just are led to a listing of what theaters will be showing FOTR, no info about the trailer. So I wrote Fandango, asking them if they were GUARANTEEING that ALL of the theaters listed would show the previews -- and, if so, why they didn't say so.
I'll let you know when/if I get an answer.

Had the same experience at the Fandango site.
I am only trusting those theaters who are beginning their run of LOTR on Friday, or those who haven't been showing it for a while who are bringing it back.
Thankfully, there are a couple of theaters in my area that are beginning new runs of LOTR...I can't wait!!!!! :)
