Zack Snyder's Superman reboot "Man of Steel" took in $12 million from special Walmart screenings, and $9 million in midnight runs on Thursday night.
That tops the $15.6 million scored earlier this summer by "Iron Man 3" which also began rolling out on a Thursday night. However, it's behind the $30.6 million that "The Dark Knight Rises" grossed in midnight previews last year.
The studio is currently projecting an $80 million opening weekend, whereas box-office analysts are more bullish with $85-100 million estimates.
This follows on from the film already opening yesterday in the Philippines and Taiwan where it scored the largest opening day ever, and the largest Warners opening ever respectively.
