I'm sure they'll be sold in many stores once the movie comes out, or even the cd.

that's interesting...the link on the other thread (courtesy of patronus) used to say $40 (which I remember thinking was a little silly)...and now it's down to $20, but out of stock. oh well. I guess this gives them a feel for how much of a following there is for this movie, at least in the theatre community.
the 2-sided version is the authentic movie theater version, kept in poster cases and used for back lighting. The back side is usually the opposite view of teh poster, complete with backwards lettering.
Ok, so, basically, if you are just going to hand the poster on your wall, buying the double sided one is a waste of money? (when a one-sided one was available)
If you are buying it solely to tack it to the wall thus putting holes in it, then yes a reprint (one sided poster) would be fine.
If you are buying it as a collector and want an "authentic" item that could potentially hold more value down then line then I'd get the theatrical one sheet (the double sided poster).
