Now THAT's a poster. :)
Unfortunately, the guy that reported to Darth Spice did not go to the screening:
"Sorry I don't have a report for you. My wife had to go in to the hospital on the 28th after I made the report about the screening, and it being my youngest's 2nd birthday on the 28th we ended up celebrating last night. If you hear of anyone that went, let me know. I have a feeling they will be playing more Star Wars movies there from time to time if it went well.
Everyone is fine here now, so I'm really bummed that we missed it!
I heard from another chicago local on the rebelscum boards that had seen a previous screening there that it was nothing special and they had played the film off a DVD or something - though I'm pretty sure that isn't entirely accurate since that doesn't sound legal and the company that owns this theater now hosts some pretty high profile entertainment there so I don't think they'd risk the wrath of lucasfilm by having an illegal showing."
I haven't been able to find any other mentions.
