Fantastic Four had a strong opening weekend but a harsh second week dropThere were two defining moments in The Fantastic Four: First Steps' box office run. Unfortunately its budget and marketing left it with a very high break-even point, which it just couldn't reach in its box office run. But where does that leave The Fantastic Four: First Steps now that its box office run is coming to an end? With the exception of The Marvels, no MCU has outright flopped at the box office. That alone could guarantee a much stronger box office performance for that one if all goes to plan.
