The latest Marvel film is the last major blockbuster of the summer, but August is off to a slow start for theaters.

Generally speaking, big movies lose a lot of business during the second weekend in theaters. The new Superman had a 53 percent drop in its second weekend in the U.S., and now, Fantastic Four had a 66 percent drop, which is six percent steeper than projections, according to Variety. So, what we're talking about here is six percent.

First Steps has made nearly $370 million globally after a big box office drop during its second weekend of release.
