$67.4 million weekend in North America for Aquaman:

More than triple what Mary Poppins and Bumblebee made.
However, it is, by a wide margin, the lowest domestic opening weekend of any of the DCEU films. Justice League had an almost $94 million opening weekend and all the rest were over $100 million.
Right now, over 85% of its gross has come from overseas, which is ridiculously high. A big part of that is because it opened two weeks ago in China, so it will be interesting to see what that mix is when its run is over.
