You see, i'm not even sure, that the POTC4 result is true-true(^^)...Plus big "IF": http://forums.boxoffice.com/index.php?/topic/678-china-box-office/?p=108878163,6m is a huge result, no movie since POTC did it, even Avatar 2 would be lucky to beat the first one.
Well, CF will have a hard time beating Thor now, so, obviously, with 99% probability, it won't happen, and it's not just because Thor might gross more than 40m, it's also because people would be tired after him, blockbuster after blockbuster - bad idea. Volga better start huge marketing campaign on Monday to take people's minds off Thor.
CF tv spots are pretty average, btw - http://www.youtube.com/user/volgafilm/videos
