Christopher Nolan's Oppenheimer is one of the best and most successful films this year. Just ask Robert Downey Jr., who called it the best film of his long and successful career.

It has proven to be a huge commercial success - when it premiered last month, it combined with Barbie for thefourth-biggest weekend in domestic box office history. It is also a critical success and, at some point, was the highest-rated Nolan film ever.

Now, Oppenheimer is about to break another record, albeit a weird one. In the coming days, the biopic will become the highest-grossing film in North America to never top the domestic box office chart.

Currently, Oppenheimer ranks second at the domestic box office and has grossed $270 million since its debut. Often, a film that make this much top the domestic box office at some point during their run. But then, Oppenheimer has been unable to achieve this feat.

The reason for this is the current number one movie Barbie, which has sat atop the domestic box office rankings. Within that period, it has grossed $541.9 million domestically, which is more than double Oppenheimer's gross.
