Prometheus Release dates

Hey there. I am sorry if I don't post this where it should. I have a simple question which google doesn't answer very nicely ( and I chose not to trust IMDB because if I do I will be pissed off). I am visiting other country, and in my own home I know Prometheus is coming out June 1st - After all it's THE movie of the year. But here, Poland, IMDB nicely tells me that it will be here JULY 20. I can't accept this as possible. What the hell? I found on another site that it will be in Poland around 18th of June, which is much better than 20 July. I am confused. Can anyone help me get a true information. I am going home in July and by then everybody would have seen it, and they may even get it off screen by then, so I am screwed. I need to see this movie. I am a fan of Scott, and I truly believe this will smash the box office. Dates for Poland? Please help. I am a die hard movie fan, give me some hope! :) Cheers
