Based on info from a cousin in Karachi who went to Artrium: You have to buy glasses only once and its upto 250 (at least that's what I was told) and movie ticket as mentioned by you. Not a bad deal, if you ask mei have heard the price would be 500 and glasses for 150... you will have to buy the glasses once i guess... i have heard that avatar will be showing on 9th... anyone got more info...??
And yes Avatar premiere is on 9th but exclusively with passes only, you need be a media personality (in most cases) to be part of it, I am currently grinding my a$$ over the passes but can't get hold of any
