$4 Million opening night probably translates to a roughly $13 Million opening weekend and probably a total of a $40 Million domestic gross.
Figure in foreign sales, DVD sales, PPV (though I don't suppose it'll be a popular in-flight movie), and the rest, and we're probably looking at total revenue of $100 Million + on a $15 Million movie - figure in advertising and the like (given the cast, talent participation has got to be minimal), the studio is probably looking at a $50 Million + profit - all on a movie made in far less than a year.
So how and when do we get into this biz? LOL.
The per-screen average is higher than any other substantial release. The picture will have legs. It should do better than $40 million. And it will do well in all ancillary markets.
