If it did $8.6 million on Friday (which includes midnight sales) I would expect it to do about that on Saturday and then finish with a Sunday total of about $25 million. Which is kind of unremarkable, but okay. I think maybe they were hoping it would do something closer to $35 million to really make it a success.
If we expect the typical 50% dropoff per week that would give it $13 million in week two, and $6 million in week three. And then it will basically be gone. That would probably make it's domestic grand total at about $50 million. Which is okay; enough to turn a small profit. But certainly not the huge success of 1997. In fact, it's the same as what Beauty and the Beast did last month without a strong ad campaign or as popular a franchise as Star Wars or as many screens, and close to half of what Lion King did.
It will be interesting to see what Titanic's numbers will be.
