Well I did read that they were doing a big push to get the film back in theaters starting on the 22nd - but I don't think they are running the trailer till the 29th... let me know what happens!
According to Box Office Mojo, LOTR is running on 216 more screens this weekend than last. This does not appear to have put it back in the top ten. I suspect a lot of repeat viewers are probably waiting for next weekend and the TT trailer.

By the way, from another item on this site, LOTR is now only $9 million behind Star Wars in unadjusted worldwide gross box office.
