There were screenings of the director's cut the week the dvd came out back in '04. The screening at the Aero will more than likely be this version.
By the way, has the '04 master of the trilogy been digitally projected anywhere? I'm not talking about throwing in the dvd, I mean Lowry's HD master. There was that 30th anniversary screening of Empire earlier this year with Harrison Ford. Did they show the '97 or was it the '04?
