It's official: Barbenheimer is one of the biggest phenomenons the box office has ever seen. The pair of blockbuster films, Barbie and Oppenheimer, have proven their critical and commercial appeal.

According to ComScore, a media analytics firm, this weekend was the fourth biggest in domestic box office history with all films combining for a gross of $301 million. Without Barbie and Oppenheimer, this feat wouldn't have been possible as both films alone contributed the sum of $235.5 million to that figure.

We found Barbenheimer's performance even more impressive when we realized that the three biggest domestic weekends were fueled by sequels in established franchises. If you hadn't already guessed, the three biggest domestic weekends were those in which Avengers: Endgame, Avengers: Infinity Wars, and Star Wars: The Force Awakens opened at the box office.

, Barbie proved to be the much bigger draw with a $155.5 million gross at the domestic box office. On the other hand, Oppenheimer pulled a little over half of that with $80.5 million.
