成本包括production和marketing. 很多片子marketing才是大头。这部片子算是大片，成本不低。尽管第一个周末表现不错，至多也不过制作成本，marketing开销还有得追呢，这还不算票房在各方面的分成。wiki上说这部片子breakeven至少需要400米票房。我听说的电影行业rule of thumb, 票房大致需要三倍制作成本才能大致持平。
“As of August 12, 2018, The Meg has grossed $45.4 million in the United States and Canada, and $101.5 million in other territories, for a total worldwide gross of $146.9 million.[7] With a production budget between $130–178 million, and another $140 million spent on advertisement, the film will need to gross at least $400 million to break-even.”
