My friend and I were discussing this. Like in the case of Pirates of the Caribbean. The had that movie done at about the same time the second one was done. We were trying to figure out why they don't release it like a couple weeks after the previous goes out of theater. The best I could come up with to explain was that they need to milk to first one financially with DVD sales, HBO, etc. He still seems to think it wouldn't change sales. Anyone know?
