ANH-3D has exceeded the budget of the original film a year ago and they are not even supposed to be working on it in earnest. Titanic is costing $18 million, some movies cost $30 million like Transformers 3, but a typical cost for a film where the 3D is done with care is about $15 million or so. I would estimate TPM cost this much but they haven't released any numbers as far as I can tell; it might be more. I doubt it's much lower, based on the fact that ANH3D already cost over $11 million in 2011 and they had only done parts of the film. Over by how much, who knows--maybe just by a bit, or maybe by another $8 million.
