“The Flash” got off to a slow start in its domestic box office sprint, earning $9.7 million in Thursday previews. That’s barely more than the $8.9 million earned by “Transformers: Rise of the Beasts” last weekend and only a bit more than the $7.5 million and $7.6 million earned by “Black Adam” and “Fast X” respectively in their Thursday preview runs.
Ten years ago, “Man of Steel” kicked off what would become the DC Films universe with a $56 million Friday (including previews) and $128 million over its Fri-Sun launch.” “The Flash” may struggle to earn as much over its opening weekend as Zack Snyder’s Superman reboot earned on its opening day.
