Producer Neal Moritz admits that the decision to make the film in 3D and shoot in Los Angeles sent the budget soaring, keeping profits low.

He tells The Hollywood Reporter, ""The movie did almost $250 million and was actually very well liked, but we made the movie for too much money.

""One, we made it in L.A. for certain reasons, and two, we decided to go to 3D - that added another $10 million.

""If I had done it in a tax-rebate state and not done 3D, it would have been considered a huge financial success for the studio.""
