Though I highly doubt it, a small part of me wants the rumor about Batman 3 being partly shot in New Orleans to be true as that is where I reside. While I'd prefer they stick with Chicago to keep continuity, I am surprised New Orleans was never thought of in the past for a Batman film. There aren't a lot of skyscrapers or very tall buildings. But there are some very specific areas that would be perfect for a narrows location or especially crime alley and there are some perfect buildings for Arkham Asylum and/or Blackgate Penitentiary. Most of the streets here look like crime alley actually, lol. Not to deter you from visiting. If they do shoot in Nola, its possible that he will visit the city as he did with Hong Kong in TDK. But this is all purely speculation. I wish they would officially announce the details as I am sure they have them all by now.
