I see it as this:
250 Million OW (250 Total) (Crosses Transformers Domestic Box office)
180 Million Monday-Thursday (Christmas week) (450) (Crosses Avengers Ultron Box office)
180 Million 2nd weekend (Christmas weekend) (610)
130 Million Monday-Thursday (new Years week) (740) (Crosses Titanic Box office)
110 Million 3rd weekend (New years weekend) (850) (Crosses Avatar Box Office)
You realize that a $110M third weekend would mean that your bottom end gross would be like $1.1B domestic right?
Also, I Am Legend opened to $77M, so it's first weekend percentage was over 30%. Some of the other films you listed opened on Wednesday.
I've seen your posts in the movie threads previously, and I know that you're knowledgeable when it comes to this sort of thing. Has anything that's been revealed recently changed your opinion on how successful TFA will be?
For myself, I didn't know that TFA would be playing straight through from Thursday to Monday. Surely that would increase your predictions, no?
I'm not sure what you mean by recently. My prediction back at the beginning of October for the GAF winter game before we had any preorder data was already pretty high ($180M OW/$680M DOM). I think I mentioned in the preorder thread that I wouldn't be that surprised to see the OW record fall if Thursday/Friday is big enough. Likewise, if the WOM is there, and Star Wars sets an opening weekend record, I wouldn't be completely shocked to see the domestic record fall. I just don't think those things are a lock yet.
It's really hard to make anything resembling an accurate prediction before a film actually launches, even if you are knowledgeable about Box Office trends. I don't think my predictions are any better than most other people here who at least have some passing knowledge of domestic box office. There are too many factors to consider. Once I have some data to look at, then sure, I am usually pretty good at extrapolating forward. We'll know whether The Force Awakens has any shot at Avatar after 10 days (unless OW ends up being the ridiculous $250-300M that some of the more insanely optimistic posters are expecting. Obviously we would know much sooner in that case).
