Chu's explanation does not make sense. So, they did not shoot the film in 3D because of time and cost. But now that Battleship bombed, they suddenly free'd up money to re-shoot in 3D and release it during March, not exactly summer blockbuster season?
Time and cost were an issue last issue during filming, but suddenly is no longer an issue following Battleship? Don't buy it.
Think about it....the movie gets pushed out 9 months (so much for the time issue), will cost more b/c of 3D (so much for the cost issue) and actually costs even more if you factor in lost marketing dollars spent (e.g. Superbowl 2012 advertising, etc.).
So, if they just decided to do it in 3D initially, they would have saved money, time and released the film during peak movie season. This apparent about face, suggest Paramount has no clue what is doing. While some folks may believe that, I don't think that is the case. Yo don't get to be a major movie studio by being clueless.
