Has posted the theaters RotJ started in.  And there's other good information on the last page.  Quotes from reviews, and other stats.

My sister took me, and I kept wandering off the line so she would throw pennies around.  So when I returned and pick um up each time going,  "Hey where'd this come from!  I'm rich!"  If you remember, I was expecting Admiral Ackbar to be 'the other' Yoda had referred to in ESB.  Simplier/dumber times.
