That is interesting. I thought the studios are now doing same day worldwide releases to prevent pirating.
I think with a movie like Avengers 2, they aren’t worried about piracy too much. Anyone who is serious about seeing it is going to crawl over broken glass to see in IMAX or 3D :)
They are a bit worried that the big ending will be revealed before it opens in the US (the one where -—— shows up and kills -—— and/or that -——— dies to save -———.....
no spoilers though
